 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]

 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 a) 1-prong and b) 3-prong offline 𝜏-leptons passing the medium BDT identification criteria. The three 𝜏-lepton trigger versions present in the 2018 trigger menu are shown. The HLT tau25 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. This version has run for the whole Run-2 period. The HLT tau25 medium BDT (1-3 precision tracks) 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 (0-3 precision tracks) 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. a) [png] [pdf] [eps] b) [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 a) 1-prong and b) 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 shown. The HLT tau25 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 (FTF) algorithm at HLT preselection level, and uses a Boosted Decision Tree algorithm for 𝜏-lepton identification. This version has run for the whole Run-2 period. The inefficiency of the FTF track multiplicity requirement 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 (1-3 precision tracks) 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.

[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.

 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]

L1 tau trigger with ET> 5 GeV in coincidence with isolated unpaired bunch (tauNoCut_unpaired) or first empty bunch (tauNoCut_firstempty) or all empty bunches (tauNoCut_cosmic). HLT is in monitoring mode (no rejection). Cosmic item is very usefull to spot also hot regions in detector. [png] [pdf]

### 7 TeV plots for approval from tau trigger group ATL-COM-DAQ-2010-042

 L1 tau trigger turn-on curve (before and after L1 calo timing correction): Fraction of the offline tau candidates matched to a L1 trigger object with ET > 5 GeV as a function of the ET of the offline tau candidate. [png] [eps] L1 tau trigger turn-on curve: Fraction of the offline tau candidates matched to a L1 trigger object with ET > 5 GeV as a function of the ET of the offline tau candidate. [png] [eps] Cumulative L1 tau trigger rate vs. ET threshold (full range): Cumulative L1 tau trigger rate as a function of the L1 tau object ET threshold, normalized to one colliding bunch pair. For a given threshold value, the objects considered have a transverse energy greater than this value. Only events passing the 10 ns requirement on the time difference measured by the two sides of the minimum bias scintillator triggers are shown for 900 GeV (blue dotted line) and 7 TeV (red dashed line) data. [png] [eps] Cumulative L1 tau trigger rate vs. ET threshold (up to 50 GeV incl. errors): Cumulative L1 tau trigger rate as a function of the L1 tau object ET threshold, normalized to one colliding bunch pair. For a given threshold value, the objects considered have a transverse energy greater than this value. Only events passing the 10 ns requirement on the time difference measured by the two sides of the minimum bias scintillator triggers are shown for 900 GeV (blue boxes) and 7 TeV (red triangles) data.
