 Efficiency of 𝜏-lepton triggers as a function of the offline 𝜏-lepton transverse momentum pT, for an ET threshold of 12 GeV and a medium isolation requirement at Level 1, and an ET threshold of 25 GeV at the High Level Trigger (HLT). The efficiencies are estimated from Monte Carlo simulation using prompt 𝜏-leptons produced in W(𝜏ν)+jets and tt events. Efficiencies are computed with respect to 1-prong offline 𝜏-leptons passing the medium BDT identification criteria. The three 𝜏-lepton trigger versions present in the 2018 trigger menu are considered. The HLT tau25 medium BDT (w/ Ntrack presel) trigger is described in ATLAS-CONF-2017-061: a requirement on the number of tracks reconstructed by a Fast Track Finder algorithm is applied at HLT preselection level to save CPU; the 𝜏-lepton identification is based on a Boosted Decision Tree algorithm. This version has run for the whole Run-2 period. The HLT tau25 medium BDT (w/o Ntrack presel) trigger is identical, except that the track multiplicity requirement is only applied to tracks from precision tracking reconstructed at a later HLT stage; this version has run for the whole 2018 data taking. The HLT tau25 medium RNN trigger uses a Boosted Regression Tree for energy calibration (instead of the pileup and response corrections applied in BDT triggers) and a Recurrent Neural Network algorithm for 𝜏-lepton identification; this version was deployed in July 2018. Only statistical uncertainties are displayed. The three HLT versions have comparable trigger rates.

 Average rate of 𝜏-lepton triggers as a function of the average number of pileup interactions, in pp collisions at √s = 13 TeV delivered by the LHC between July and October 2018, corresponding to an integrated luminosity of 36.8 fb-1. Rates are shown for a) the single-tau trigger with an ET threshold of 160 GeV at the High Level Trigger (HLT), and b) the di-tau trigger with a L1Topo and a jet requirement at Level 1, and ET thresholds of 35 and 25 GeV at the HLT. The medium BDT (1-3 fast tracks) trigger described in ATLAS-CONF-2017-061 applies a requirement on the number of tracks reconstructed by a Fast Track Finder algorithm at HLT preselection level, and uses a Boosted Decision Tree algorithm for 𝜏-lepton identification. The track preselection reduces CPU and rates but induces inefficiency for 3-prong 𝜏-leptons at high pileup. The medium BDT (1-3 precision tracks) trigger is identical, except that the track multiplicity requirement is applied to precision tracks reconstructed at a later HLT stage. Efficiency at high pileup is recovered at the expense of a slight rate increase. The medium RNN (0-3 precision tracks) trigger applies a requirement on the number of precision tracks, and uses a Recurrent Neural Network algorithm for 𝜏-lepton identification. The larger increase in the RNN di-tau trigger rate at high pileup comes from HLT tau candidates with no associated track, which were included in the RNN trigger to recover efficiency at low ET. The single-tau trigger does not exhibit this behaviour due to its high-ET threshold. a) [png] [pdf] [eps] b) [png] [pdf] [eps]

[png] [pdf] [eps] Efficiency of 𝜏-lepton triggers as a function of the average number of pileup interactions, for an ET threshold of 12 GeV and a medium isolation requirement at Level 1, and an ET threshold of 25 GeV at the High Level Trigger (HLT). The efficiencies are estimated from Monte Carlo simulation using prompt 𝜏-leptons produced in W(𝜏ν)+jets and tt events. Efficiencies are computed with respect to 3-prong offline 𝜏-leptons with pT > 30 GeV passing the medium BDT identification criteria. The three 𝜏-lepton trigger versions present in the 2018 trigger menu are considered. The HLT tau25 medium BDT (w/ Ntrack presel) trigger is described in ATLAS-CONF-2017-061: a requirement on the number of tracks reconstructed by a Fast Track Finder algorithm is applied at HLT preselection level to save CPU; the 𝜏-lepton identification is based on a Boosted Decision Tree algorithm. This version has run for the whole Run-2 period. The inefficiency of the Ntrack preselection at high pileup is due to the larger number of fake tracks reconstructed from random hits alignment in the inner detector. The HLT tau25 medium BDT (w/o Ntrack presel) trigger is identical, except that the track multiplicity requirement is only applied to tracks from precision tracking reconstructed at a later HLT stage; this version has run for the whole 2018 data taking. The HLT tau25 medium RNN trigger uses a Boosted Regression Tree for energy calibration (instead of the pileup and response corrections applied in BDT triggers) and a Recurrent Neural Network algorithm for 𝜏-lepton identification; this version was deployed in July 2018.

[png][pdf][eps] Comparison of the ATLAS HLT expected single-tau trigger efficiency in Run-I and Run-II simulations. The efficiency is computed for offline reconstructed tau candidates with transverse momentum above 20 GeV, one or three tracks and passing the offline medium identification criteria [Eur.Phys.J.C75(2015)303] in simulated Z→ ττ events, where one tau lepton decays leptonically and the other hadronically. The correspondent online tau candidate is required to have a transverse momentum of at least 35 GeV, between one and three tracks and passing the online medium identification. The efficiency is plotted as function of the transverse momentum of the offline tau candidate. Error bars are statistical uncertainties. The overall improvement in the trigger efficiency expected in Run-II is due to the new high-level trigger strategy which includes a more precise energy calibration, a faster tracking and an online identification requirement closer to the one used in the offline tau reconstruction.

The tau trigger considered here has calorimetric isolation and a pT threshold of 11 GeV at L1, a 20 GeV requirement on pT, the number of tracks restricted to three or less, and medium selection on the BDT score at the EF. The error bars correspond to the statistical uncertainty on the efficiency.

 The measured resolution of the transverse energy (pT), with respect to the offline tau candidates identified by the Boosted Decision Tree (BDT) algorithm, at the second level of the ATLAS tau trigger chain in 2012 (level two, L2). The resolution is measured with the full ATLAS 2012 dataset (20.3 fb-1), using a tag-and-probe analysis with Z -> τ_mu τ_had events similar to that described in the 2011 ATLAS tau trigger performance conference paper (ATLAS‐CONF­‐2013­‐006). Data (dots) are compared to the simulation of the background and signal PDFs (stacked filled histograms). The statistical errors on the sum of the signal and background PDFs are shown (grey, hashed). The signal process, where a Z boson decays into two tau leptons, is shown in blue. The W+jets background, where a real muon comes from the W decay and a jet is misidentified as a hadronic tau candidate, is shown in yellow. The ‘Same Sign’ background, dominated by QCD multi-jet production where one jet fakes a prompt muon and the other fakes a hadronic tau candidate, is shown in green. This background is estimated in a data-driven manner from same-sign data events. The remaining SM processes which have smaller contributions, such as Z boson decays into two muons or two electrons, are shown in brown. The reconstructed energy at L2 is overestimated since it is a scalar sum of energy deposits within a square Region of Interest (RoI), and so it is sensitive to the geometry of the RoI.

 ΔZ0 distribution taken from 2012 (8 TeV) data, with a peak of eighteen interactions per bunch crossing. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 difference with respect to the lead track Z0. Large values of ΔZ0 correspond to pileup tracks. A Lorentzian function is fitted to the distribution and the quoted value of σ integrates 68% of the area of the central peak. Dependence of the trigger variables on pileup is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] ΔZ0 distribution from Z->ττ MC events with an average of eight interactions per bunch crossing. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 difference with respect to the lead track Z0. Large values of ΔZ0 correspond to pileup tracks. The wide Gaussian distribution corresponds to pileup tracks while the central peak, displayed in the upper right hand side corner, corresponds to the main interaction tracks. A Lorentzian function is fitted to the central peak and the quoted value of the σ integrates 68% of the area. Dependence of the trigger variables on pileup is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] Average L2 SumPtRatio as a function of the average number of interactions per bunch crossing in Z->ττ events. The SumPtRatio is the ratio of the scalar sum of the pT of all the tracks in the isolation region, defined as annulus 0.1<ΔR<0.3 with respect to the leading track in the RoI, to the scalar sum of the pT of all the tracks in the core region, defined as the ΔR<0.1 cone around the leading track. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 distance with respect to the lead track. Pileup dependence is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] Marginal efficiencies for L2 SumPtRatio as well as L2 EM radius calculated in cones of ΔR < 0.2 and 0.4 are shown as a function of the average number of interactions per bunch crossing. EM radius is the electromagnetic energy weighted radius and SumPtRatio is the ratio of the scalar sum of pT of all tracks in an isolation region to that in a core region. The isolation region is the annulus 0.1<ΔR<0.3 around the direction of the highest momentum track, while the core region is defined to be a cone of radius ΔR<0.1. Average number of interactions per bunch crossing provides a measure of pileup. These marginal efficiencies have been calculated with respect to a specific L2 trigger selection optimized for low pT taus, L2_tau20_medium1. [png] [eps] [pdf]

 Performance of the multivariate‐based tau triggers at EF. The signal efficiency is defined with respect to the offline identified tau candidates from the truth tau and the background rejection is from a jet. The figure shows multi‐prong tau trigger candidates for BDT-­ and LLH-­based triggers. The trigger decision is optimized to be 85% and 80% with respect to the offline candidates for 1­‐prong and multi-­prong, respectively. [png] [eps] Shown are the trigger rates as a function of instantaneous luminosity for combined tau triggers. A linear rise in rates is seen in data taken after the April technical stop. This is due to the small cone size (0.2) and implementation of ΔZ selection with respect to the leading track (abs(ΔZ) < 2mm) at the HLT. The numerical figures in the name of each trigger chain correspond to the transverse energy or momentum threshold applied at EF. [png] [eps]

Data has been recorded in the first 13 TeV collisions in 2015. The data are compared to a signal Z→ττ Monte Carlo and a combined background consisting of Z→ll, W+jets, and Top Monte Carlo and a data driven multijet estimate. Only statistical uncertainties are shown. The ratio of the observed data to the expected signal and background events is also shown, where the red band shows the statistical uncertainty on the total expectation. Event selections and background estimations are described in ATL-PHYS-PUB-2015-025 and in Eur. Phys. J. C75 (2015) 303. [png] [pdf] [eps]

[png][pdf][eps] Comparison of the ATLAS HLT expected single-tau trigger efficiency in Run-I and Run-II simulations. The efficiency is computed for offline reconstructed tau candidates with transverse momentum above 20 GeV, one or three tracks and passing the offline medium identification criteria [Eur.Phys.J.C75(2015)303] in simulated Z→ ττ events, where one tau lepton decays leptonically and the other hadronically. The correspondent online tau candidate is required to have a transverse momentum of at least 35 GeV, between one and three tracks and passing the online medium identification. The efficiency is plotted as function of the transverse momentum of the offline tau candidate. Error bars are statistical uncertainties. The overall improvement in the trigger efficiency expected in Run-II is due to the new high-level trigger strategy which includes a more precise energy calibration, a faster tracking and an online identification requirement closer to the one used in the offline tau reconstruction.

 Level 1 rates before prescale versus the instantaneous luminosity measured by ATLAS for L1 single-tau and combined tau+X chains. ‘TAU’, ‘EM’, ‘J’ and ‘XE’ indicate the type of L1 object, tau, electron, jet or missing energy, respectively. The digit before these names indicates the object multiplicity, while the digits after correspond to the ET requirement, e.g. a L1 ET > 30 GeV for L1 TAU30. ‘IM’ and ‘HI’ indicate that isolation requirements are applied. The data have been collected at a center-of-mass energy of 13 TeV in 2015, from the 6th to the 12th of July.

 Comparison of the ATLAS HLT expected single-tau trigger efficiency in Run-I and Run-II simulations. The efficiency is computed for offline reconstructed tau candidates with transverse momentum above 20 GeV, one or three tracks and passing the offline medium identification criteria [Eur.Phys.J.C75(2015)303] in simulated Z→ ττ events, where one tau lepton decays leptonically and the other hadronically. The correspondent online tau candidate is required to have a transverse momentum of at least 35 GeV, between one and three tracks and passing the online medium identification. The efficiency is plotted as function of the transverse momentum of the offline tau candidate. Error bars are statistical uncertainties. The overall improvement in the trigger efficiency expected in Run-II is due to the new high-level trigger strategy which includes a more precise energy calibration, a faster tracking and an online identification requirement closer to the one used in the offline tau reconstruction.

 The measured resolution of the transverse energy (pT), with respect to the offline tau candidates identified by the Boosted Decision Tree (BDT) algorithm, at the second level of the ATLAS tau trigger chain in 2012 (level two, L2). The resolution is measured with the full ATLAS 2012 dataset (20.3 fb-1), using a tag-and-probe analysis with Z -> τ_mu τ_had events similar to that described in the 2011 ATLAS tau trigger performance conference paper (ATLAS‐CONF­‐2013­‐006). Data (dots) are compared to the simulation of the background and signal PDFs (stacked filled histograms). The statistical errors on the sum of the signal and background PDFs are shown (grey, hashed). The signal process, where a Z boson decays into two tau leptons, is shown in blue. The W+jets background, where a real muon comes from the W decay and a jet is misidentified as a hadronic tau candidate, is shown in yellow. The ‘Same Sign’ background, dominated by QCD multi-jet production where one jet fakes a prompt muon and the other fakes a hadronic tau candidate, is shown in green.

 ΔZ0 distribution taken from 2012 (8 TeV) data, with a peak of eighteen interactions per bunch crossing. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 difference with respect to the lead track Z0. Large values of ΔZ0 correspond to pileup tracks. A Lorentzian function is fitted to the distribution and the quoted value of σ integrates 68% of the area of the central peak. Dependence of the trigger variables on pileup is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] ΔZ0 distribution from Z->ττ MC events with an average of eight interactions per bunch crossing. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 difference with respect to the lead track Z0. Large values of ΔZ0 correspond to pileup tracks. The wide Gaussian distribution corresponds to pileup tracks while the central peak, displayed in the upper right hand side corner, corresponds to the main interaction tracks. A Lorentzian function is fitted to the central peak and the quoted value of the σ integrates 68% of the area. Dependence of the trigger variables on pileup is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] Average L2 SumPtRatio as a function of the average number of interactions per bunch crossing in Z->ττ events. The SumPtRatio is the ratio of the scalar sum of the pT of all the tracks in the isolation region, defined as annulus 0.1<ΔR<0.3 with respect to the leading track in the RoI, to the scalar sum of the pT of all the tracks in the core region, defined as the ΔR<0.1 cone around the leading track. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 distance with respect to the lead track. Pileup dependence is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] Marginal efficiencies for L2 SumPtRatio as well as L2 EM radius calculated in cones of ΔR < 0.2 and 0.4 are shown as a function of the average number of interactions per bunch crossing. EM radius is the electromagnetic energy weighted radius and SumPtRatio is the ratio of the scalar sum of pT of all tracks in an isolation region to that in a core region. The isolation region is the annulus 0.1<ΔR<0.3 around the direction of the highest momentum track, while the core region is defined to be a cone of radius ΔR<0.1. Average number of interactions per bunch crossing provides a measure of pileup. These marginal efficiencies have been calculated with respect to a specific L2 trigger selection optimized for low pT taus, L2_tau20_medium1. [png] [eps] [pdf]

The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 difference with respect to the lead track Z0. Large values of ΔZ0 correspond to pileup tracks. A Lorentzian function is fitted to the distribution and the quoted value of σ integrates 68% of the area of the central peak. Dependence of the trigger variables on pileup is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] ΔZ0 distribution from Z->ττ MC events with an average of eight interactions per bunch crossing. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 difference with respect to the lead track Z0. Large values of ΔZ0 correspond to pileup tracks. The wide Gaussian distribution corresponds to pileup tracks while the central peak, displayed in the upper right hand side corner, corresponds to the main interaction tracks. A Lorentzian function is fitted to the central peak and the quoted value of the σ integrates 68% of the area. Dependence of the trigger variables on pileup is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] Average L2 SumPtRatio as a function of the average number of interactions per bunch crossing in Z->ττ events. The SumPtRatio is the ratio of the scalar sum of the pT of all the tracks in the isolation region, defined as annulus 0.1<ΔR<0.3 with respect to the leading track in the RoI, to the scalar sum of the pT of all the tracks in the core region, defined as the ΔR<0.1 cone around the leading track. The ΔZ0 of a track associated with an L2 tau trigger object is defined as the Z0 distance with respect to the lead track. Pileup dependence is avoided when only tracks with -2mm < ΔZ0 < 2mm are considered. [png] [eps] [pdf] Marginal efficiencies for L2 SumPtRatio as well as L2 EM radius calculated in cones of ΔR < 0.2 and 0.4 are shown as a function of the average number of interactions per bunch crossing. EM radius is the electromagnetic energy weighted radius and SumPtRatio is the ratio of the scalar sum of pT of all tracks in an isolation region to that in a core region. The isolation region is the annulus 0.1<ΔR<0.3 around the direction of the highest momentum track, while the core region is defined to be a cone of radius ΔR<0.1. Average number of interactions per bunch crossing provides a measure of pileup. These marginal efficiencies have been calculated with respect to a specific L2 trigger selection optimized for low pT taus, L2_tau20_medium1. [png] [eps] [pdf]

 Efficiency with respect to the offline identified tau candidates as a function of number of vertices measured in 2011. The efficiency of the tau20_medium trigger measured using a tag and probe analysis with Z ­‐> ττ ­‐> μh events collected by ATLAS in 2011. The term tau20_medium implies a 20 GeV requirement on the transverse energy at EF and medium selections on the shower shape variables. The analysis follows closely the tau ID efficiency measurement ATLAS-CONF­-2011-­152. [png] [eps] Expected efficiency in 2012 with respect to the offline identified tau candidates as a function of number of vertices. The tau trigger is rerun on the full 2011 dataset from unbiased Z ­‐> ττ ‐> μh events, where muon trigger is used to collect Z ­‐> ττ ‐> μh data and measure the efficiency of the tau20_medium trigger by a tag and probe method. The term tau20_medium implies a 20 GeV requirement on the transverse energy at EF and medium selections on the shower shape variables. In 2012, smaller calorimeter cone size of 0.2 compared to 0.4 in 2011 and implementation of ΔZ selection with respect to the leading track (abs(ΔZ) < 2mm) will provide robustness against pile-­up. The analysis follows closely the tau ID efficiency measurement ATLAS-­CONF-­2011-­152. [png] [eps] Expected efficiency in 2012 with respect to the offline identified tau candidates as a function of the offline tau pT. The tau trigger is rerun on the full 2011 dataset from unbiased Z ‐> ττ ‐> μh events, where muon trigger is used to collect Z ‐> ττ ­‐> μh data and measure the efficiency of the tau20_medium trigger by a tag and probe method. The selection applied at EF is based on multivariate technique. The figure is based on Boosted Decision Tree method. In 2012, the BDT-­‐based tau triggers will be used as the baseline.

[png] [eps] Performance of the multivariate‐based tau triggers at EF. The signal efficiency is defined with respect to the offline identified tau candidates from the truth tau and the background rejection is from a jet. The figure shows 1‐prong tau trigger candidates for BDT-­ and LLH-­based triggers. The trigger decision is optimized to be 85% and 80% with respect to the offline candidates for 1­‐prong and multi-­prong, respectively. [png] [eps] Performance of the multivariate‐based tau triggers at EF. The signal efficiency is defined with respect to the offline identified tau candidates from the truth tau and the background rejection is from a jet. The figure shows multi‐prong tau trigger candidates for BDT-­ and LLH-­based triggers. The trigger decision is optimized to be 85% and 80% with respect to the offline candidates for 1­‐prong and multi-­prong, respectively. [png] [eps] Shown are the trigger rates as a function of instantaneous luminosity for combined tau triggers. A linear rise in rates is seen in data taken after the April technical stop. This is due to the small cone size (0.2) and implementation of ΔZ selection with respect to the leading track (abs(ΔZ) < 2mm) at the HLT. The numerical figures in the name of each trigger chain correspond to the transverse energy or momentum threshold applied at EF. [png] [eps]

 Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains. The numbers in the item names correspond to ET requirements at EF for a given trigger type, e.g. an electron candidate with ET > 15 GeV in e15. The saturation in the rates of single tau trigger and a not fully linear increase in combined triggers are due to the 0.4 cone size used to calculate the energy at L2 and EF, which is found to be very sensitive to high pile-up. The data have been collected at a center-of-mass energy of 7 TeV in August 2011. [png] [eps] Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains. The numbers in the item names correspond to ET requirements at EF for a given trigger type, missing transverse energy > 35 GeV in xe35. MET significance, denoted by xs, is defined as MET/(a(sqrt(SumEt)-b)) where a, b are constants determined from the data. In an item containing xsZ term, the trigger requires xs to be above Z/10. The decrease in tau+xs triggers rate is due to the increase in the SumEt at high luminosity. The data have been collected at a center-of-mass energy of 7 TeV in August 2011. [png] [eps] Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains collected from September to October 2011. The numbers in the item names correspond to ET requirements at EF for a given trigger type, e.g. an electron candidate with ET > 15 GeV in e15vh, where vh implies that the η dependent ET selections were applied at L1 and the energy in core of the hadronic calorimeter is required to be smaller than 1 GeV. The data have been collected at a center-of-mass energy of 7 TeV in 2011. [png] [eps]

 EF_tau20_medium1 efficiency: Efficiency of the EF\_tau20\_medium1 trigger chain with respect to offline reconstructed tau candidates, as a function of the offline $\pt$. The trigger includes a strict requirement on the number of tracks associated to the trigger object in addition to the regular 'medium' selection. The measurement was made using a tag and probe analysis with $Z\rightarrow\tau\tau\rightarrow\mu h$ events in 2011 data. The tau candidates are required to pass medium identification criteria. The analysis follows closely the method from the $Z\rightarrow\tau\tau$ cross-section measurement http://arxiv.org/abs/1108.2016. [png] [eps]

### Plots for Winter 2012 ATL-COM-DAQ-2012-001

 Level 1 rates before prescale versus the instantaneous luminosity measured by ATLAS for L1 tau items that seed tau chains at HLT. The last digits in the L1 item name correspond to the ET requirement, e.g. a L1 ET > 11 GeV for L1 TAU11. The data have been collected at a center-of-mass energy of 7 TeV in 2011. [png] [eps] Cross-section (rate to luminosity ratio) versus the average number of interactions per bunch crossings measured by ATLAS for L1 tau items that seed tau chains at HLT. The last digits in the L1 item name correspond to the ET requirement, e.g. a L1 ET > 11 GeV for L1 TAU11. The data have been collected at a center-of-mass energy of 7 TeV in 2011. [png] [eps] Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains. The numbers in the item names correspond to ET requirements at EF for a given trigger type, e.g. a muon candidate with ET > 15 GeV in mu15. The saturation in the rates of single and di-tau triggers, while a not fully linear increase in combined triggers are due to the 0.4 cone size used to calculate the energy at L2 and EF, which is found to be very sensitive to high pile-up. The data have been collected at a center-of-mass energy of 7 TeV from March to July in 2011. [png] [eps] Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains. The numbers in the item names correspond to ET requirements at EF for a given trigger type, e.g. an electron candidate with ET > 15 GeV in e15. The saturation in the rates of single tau trigger and a not fully linear increase in combined triggers are due to the 0.4 cone size used to calculate the energy at L2 and EF, which is found to be very sensitive to high pile-up. The data have been collected at a center-of-mass energy of 7 TeV in August 2011. [png] [eps] Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains. The numbers in the item names correspond to ET requirements at EF for a given trigger type, missing transverse energy > 35 GeV in xe35. MET significance, denoted by xs, is defined as MET/(a(sqrt(SumEt)-b)) where a, b are constants determined from the data. In an item containing xsZ term, the trigger requires xs to be above Z/10. The decrease in tau+xs triggers rate is due to the increase in the SumEt at high luminosity. The data have been collected at a center-of-mass energy of 7 TeV in August 2011. [png] [eps] Event Filter output rates versus the instantaneous luminosity measured by ATLAS for selected HLT tau chains collected from September to October 2011. The numbers in the item names correspond to ET requirements at EF for a given trigger type, e.g. an electron candidate with ET > 15 GeV in e15vh, where vh implies that the η dependent ET selections were applied at L1 and the energy in core of the hadronic calorimeter is required to be smaller than 1 GeV. The data have been collected at a center-of-mass energy of 7 TeV in 2011.

 Figure 1: Comparison of the L1 tau candidate ET distribution for 900 GeV data and MB MC. The cut off at 6 GeV corresponds to the L1_TAU5 threshold. [png] [eps] Figure 2:Comparison of the L1 tau candidate EM isolation distribution for 900 GeV data and MB MC. [png] [eps] Figure 3: Comparison of the tau candidate E/ distribution at L2 for 900 GeV data and MB MC. [png] [eps] Figure 4: Comparison of the tau candidate EM fraction distribution at L2 for 900 GeV data and MB MC. The values below zero and above one appear because the EM and HAD energies can be negative due to noise fluctuations. [png] [eps] Figure 5: Comparison of the tau candidate number of tracks distribution at L2 for 900 GeV data and MB MC. [png] [eps] Figure 6: Comparison of the tau candidate E/ distribution at EF for 900 GeV data and MB MC. [png] [eps] Figure 7:Comparison of the tau candidate EM radius distribution at EF for 900 GeV data and MB MC.

[png] [eps] Figure 9: Distribution for number of tracks associated to the tau candidate at EF for 900 GeV data and MB MC. The difference between the number of tracks distribution at L2 (Fig.~5) and that at EF (Fig.~9) is due to the difference in the requirement for the minimum $p_T$ of the track. At L2 the minimum $p_T$ requirement is 1.5GeV, while at the EF it is 1GeV.

[png] [eps] Figure 12:Cumulative L1 tau trigger rate as a function of the L1 tau object E/ threshold, normalized to one colliding bunch pair. For a given threshold value, the objects considered have a transverse energy greater than this value. [png] [eps] Figure 13:E/ of the calorimeter cluster found at L2. The solid histogram represents a run with cosmic ray and collisions events while the dashed filled histogram represents a cosmic ray run only.
