Single electron trigger efficiencies for 2018 (with scale-factors) and full Run 2 ATL-COM-DAQ-2019-049

* ATL-COM-DAQ-2019-049

Efficiency of the lowest unprescaled single electron trigger combination (logical OR of HLT_e26_lhtight_nod0_ivarloose, HLT_e60_lhmedium_nod0 and HLT_e140_lhloose_nod0) in 2018 data, compared to Z→ ee Powheg Pythia Monte Carlo. A total of 47.8 fb^-1 of proton-proton collision data at a center-of-mass energy of √ s = 13 TeV is used. The efficiency is given as a function of the offline electron transverse energy, E_T , where the offline electron fulfills a tight offline identification requirement as well as a tight offline isolation requirement (FCTight isolation working point). The η dependency is integrated between \|η\| < 2.47, for μ the integration is done over its full range. The efficiency is determined using a Z tag-and-probe method. The vertical error bars show statistical and systematic uncertainties on the efficiency, obtained as described in ATLAS Collaboration, arxiv: 1902.04655. The horizontal error bars reflect the bin width. No background subtraction is applied.	[png] [eps] [pdf]

Trigger efficiency in 2018 data over the corresponding Z→ ee Powheg Pythia Monte Carlo value of the lowest unprescaled single electron trigger combination (logical OR of HLT_e26_lhtight_nod0_ivarloose, HLT_e60_lhmedium_nod0 and HLT_e140_lhloose_nod0). The ratio is shown in dependency of the offline electron transverse energy E_T and pseudorapidity η. The electron is required to fulfill the tight offline identification working point as well as a tight offline isolation requirement (FCTight offline isolation working point). The value shown is the central value of the ratio, which is gained in an average over all systematic variations. No uncertainty on the value is given here. Background subtraction is applied to calculate the ratio.	[png] [eps] [pdf]
Efficiency of the lowest unprescaled single electron trigger combination in 2015 (logical OR of HLT_e24_lhmedium_L1EM20VH, HLT_e60_lhmedium and HLT_e120_lhloose) and 2016-2018 (logical OR of HLT_e26_lhtight_nod0_ivarloose, HLT_e60_lhmedium_nod0 and HLT_e140_lhloose_nod0) data, compared to Z→ ee Powheg Pythia Monte Carlo. A total of 47.8 fb^-1 of proton-proton collision data at a center-of-mass energy of √ s = 13 TeV is used for 2018 data, whereas for 2015, 2016 and 2017 3.2 fb^-1, 32.9 fb^-1 and 43.9fb^-1 are used, respectively. The efficiency is given as a function of the offline electron transverse energy, E_T, where the offline electron fulfills a tight offline identification requirement as well as a tight offline isolation requirement (FCTight isolation working point). The η dependency is integrated between \|η\| < 2.47, for μ the integration is done over its full range. The efficiency is determined using a Z tag-and-probe method. The vertical error bars show statistical and systematic uncertainties on the efficiency, obtained as described in ATLAS Collaboration, arxiv: 1902.04655. No background subtraction is applied. The horizontal error bars reflect the bin width. The trigger efficiency in 2015 is highest because no online isolation requirement and a looser online identification requirement was applied. The inefficiency observed in 2016 is due to too stringent online identification optimisation with respect to the previous offline selection criteria. The efficiency improvements in 2017-2018 are due to usage of more effective online algorithms (introduction of neural network based ringer selection) which allowed better alignment of the online selection (looser track-calorimeter matching, removal of likelihood-only calorimeter selection) with the final offline selection for Run 2.

Sources of inefficiency for single electron triggers with 2017 data ATL-COM-DAQ-2018-007

* ATL-COM-DAQ-2018-007

Sources of inefficiency for the e26_lhtight_nod0_ivarloose trigger at each selection step in the High Level Trigger (HLT) with respect to the offline reconstruction and the corresponding Level-1 (L1) requirements in a data run taken in October 2017. Electron reconstruction at the HLT is performed in the Region of Interest provided by the L1 and proceeds via a series of sequential steps. First, a Fast Reconstruction and Selection is performed; this constitutes a fast calorimeter reconstruction and neural-network-based selection using shower shape information, followed by a fast track reconstruction and electron pre-selection in which, in addition to track quality requirements, the calorimeter-tracking position matching quantities are used. In the Precision Calo step, HLT clusters are reconstructed and then calibrated using a multivariate technique, mirroring the offline identification. Subsequently, Precision Tracks are reconstructed and extrapolated to the second layer of the EM calorimeter. Electron candidates are then constructed by matching clusters to these tracks. The Precision Electron identification primarily utilises a Likelihood Discriminant based on calorimeter cluster shower shape, tracking and track-cluster matching variables, in addition to a required minimum number of hits in the (first layer of the) Pixel detector, n_Pixel (n_IBL ). The inset plot provides supplementary information on these contributions to the Precision Electron requirement, which are mutually non-exclusive. Additionally, isolation requirements on the Precision Electron candidate may be applied; if the candidate fails the Precision Electron selection but passes isolation, Precision Electron only is filled; if the candidate passes Precision Electron buts fails isolation, Isolation only is filled; if both fail, Combined Precision Electron & Isolation is filled. The L1 requirement for this trigger, EM22VHI, requires an isolated electromagnetic cluster with E_T > 22 GeV. The offline reconstructed electron is required to have a transverse energy of E_T > 27 GeV and pass the likelihood-based tight identification (ID). The e26_lhtight_nod0_ivarloose trigger requires an electron candidate with E_T > 26 GeV satisfying the likelihood-based tight ID, without applying transverse impact parameter requirements, but applying variable-size cone isolation, p_T^varcone0.2/E_T < 0.1. The inefficiencies are determined by the percentage of candidates that pass the offline ID, but fail the online ID at the indicated step, measured with a tag-and-probe method using Z → ee decays providing approximately 2.5 10⁵ suitable probe electrons. The sizes of the contributions of the individual selection steps to the overall inefficiency depend on the p_T of the electron, and therefore, in this plot, depend on the p T spectrum of the probe-electron of the Z →ee test sample.

The offline reconstructed electron is required to have a transverse energy of E_T > 61 GeV and pass the likelihood-based tight identification (ID). The e60_lhmedium_nod0 trigger requires an electron candidate with E_T > 60 GeV satisfying the likelihood-based tight ID, without applying transverse impact parameter requirements or isolation (the associated categories are retained here for consistency with other plots). The inefficiencies are determined by the percentage of candidates that pass the offline ID, but fail the online ID at the indicated step, measured with a tag-and-probe method using Z → ee decays providing approximately 1.5 10⁴ suitable probe electrons. The sizes of the contributions of the individual selection steps to the overall inefficiency depend on the p_T of the electron, and therefore, in this plot, depend on the p_T spectrum of the probe-electron of the Z → ee test sample.

Performance of Ringer in Trigger egamma for WCCI2018 ATL-COM-DAQ-2018-005

https://cds.cern.ch/record/2301712

Electron trigger efficiency, measured with data recorded Jun 05 -- Oct 08 2017, as a function of the offline reconstructed electron candidate's transverse energy (E_T). The trigger efficiency was measured on electrons or positrons from Z boson decay using the data-driven tag-and-probe method. The offline reconstructed electron is required to be within the ATLAS precision region (|η|<2.47) and to pass the strictest offline selection. The efficiency is computed for two electron triggers requiring their most restrictive operating point and transverse energy above 28~GeV. The only difference between the two triggers is in the initial HLT selection, restricted to calorimeter information. The blue circles represent the efficiencies for the electron triggers operating with an ensemble of neural networks fed by ring-shaped energy description (Ringer), while the black triangles show the efficiencies for the electron triggers without Ringer, based on a previously used cut-based selection. Statistical uncertainties are too small to be visible.

Top: Experimental observations for the offline reconstructed E_ratio quantity measured with data recorded Jun 05 -- Aug 24 2017. E_ratio is the difference in energy between the highest and second highest energy deposit in the cells of the first calorimeter sampling divided by the sum. The histograms are filled using probe electrons or positrons from Z boson decays acquired by employing the data-driven tag-and-probe method and requiring the least strict offline selection. For comparing the shapes of the two distributions with reasonable statistics in each bin, bins are merged in both histograms simultaneously to have at least 30 entries and entries are removed at random from the histogram with more statistics until their total matches. The black line shows entries collected by a trigger with a selection based on the ensemble of neural networks fed by ring-shaped energy description (Ringer), while the blue area represents the data collected by the electron triggers without Ringer, based on a previously used cut-based selection. Bottom: the experimental observations of the residuals (black circles) computed by the ratio of the difference of the histogram entries and the corresponding baseline uncertainty (σ_ref per sample. σ_ref is computed as the squared root of the number of entries per sample. The residuals are small (σ_ref<0.3) and oscillate freely along the positive and negative axis, which suggests that there is no significant impact when replacing cut-based selection with the Ringer approach.

Rate of the lowest unprescaled single electron trigger as a function of the E_T threshold in √s = 13 TeV p-p data collected in 2016 ATL-COM-DAQ-2017-039

https://cds.cern.ch/record/2266683

Rate (in Hz) of the isolated single electron trigger as a function of the E_T threshold at the high-level trigger (HLT) in the [26,72] GeV range, for the same likelihood-based tight identification and Level-1 selections. The rate is measured in a dataset collected at a constant instantaneous luminosity of 8x10³³ cm^-2s^-1 at √s = 13 TeV, while the contribution from W, Z and multi-jet production is estimated with Monte Carlo. The dominant uncertainty on the multi-jet rate is evaluated with a data-driven technique: the rate vs E_T plot is obtained in a multi-jet enriched region by inverting the HLT track-based electron isolation, and the bin-by-bin disagreement between data and Monte Carlo is applied as a systematic uncertainty on the multi-jet process. The total expected rate is in agreement with the measured value for all the thresholds considered. A major fraction of the rate comes from physics processes of interest such as W and Z production, while a relevant but not dominant background comes from jets mis-identified as electrons.

Level-1 EM isolation optimization for 2017 data taking ATL-COM-DAQ-2017-033

https://cds.cern.ch/record/2262803

Efficiency of the Level-1 triggers, L1_EM24VHI and new L1_EM24VHIM, as a function of the offline electron candidate's transverse energy (E_T). The Level-1 triggers require an isolated electromagnetic (EM) cluster with E_T > 24 GeV. "V" indicates that η-dependent trigger thresholds are applied. "H" indicates that the transverse energy in the hadronic calorimeter behind the core of the EM cluster relative to the EM cluster transverse energy is less than a certain value. Triggers including "I" ("IM") in their name have isolation applied for EM clusters with E_T < 50 GeV, where the transverse energy in an annulus of calorimeter towers around the EM candidate relative to the EM cluster E_T is required to be less than max{2 GeV, E_T/8 - 1.8 GeV} (max{1 GeV, E_T/8 - 2.0 GeV}). The efficiency is measured with respect to the offline reconstructed electron candidates satisfying a likelihood-based tight identification. The efficiencies are measured with a tag-and-probe method using Z → ee decays in data using trigger reprocessings. New Level-1 EM medium isolation cuts have been implemented to reduce the rate of the lowest unprescaled Level-1 triggers while keeping the efficiency loss as low as possible, to cope with the increasing luminosity in 2017, and are compared with the default isolation cuts used for 2016 data taking.

L1 EM trigger rates using the full 2016 dataset ATL-COM-DAQ-2017-021

https://cds.cern.ch/record/2260464

Output rates of Level-1 EM triggers as a function of the uncalibrated instantaneous luminosity measured online during the 2016 proton-proton data taking at a center-of-mass energy of 13 TeV. An |η| dependent requirement on the energy deposited in the electromagnetic calorimeter is applied in addition to a veto on energy deposited in the hadronic calorimeter. Single triggers have an additional EM isolation requirement on the energy deposited in the 12 EM Trigger Towers surrounding the central 2x2 EM Trigger Towers. Rates are shown only for unprescaled triggers. All trigger rates show a linear dependency with instantaneous luminosity.

Electron detection efficiency over Z → ee simulation data for the trigger fast calorimeter sub-step as a function of the offline reconstructed electron candidate’s pseudorapidity (η). The efficiency was measured with a tag-and-probe method for Z → ee decays. The offline reconstructed electron matched to the trigger candidate is required to be within the precision region of the calorimeter and to have at least 25 GeV. Efficiency for the candidates satisfying the medium criteria on two chains are shown. On black lies the standard hard-cut based approach (benchmark) upon the fast calorimeter sub-step, whereas on blue this sub-step is replaced by the ringer approach, set to operate with the same overall detection rate as the benchmark. Neither approaches have pile-up dependency correction. The ringer approach uses ring-shaped calorimeter information and a multivariate discriminator (neural based) for e/γ identification, which can improve background rejection for a given signal efficiency level. The error bars show statistical uncertainties.

Electron and photon trigger rates in 2015 ATLAS data ATL-COM-DAQ-2015-103 (July 23, 2015)

http://cds.cern.ch/record/2034886

Output rates of single electron triggers as a function of the instantaneous luminosity during the 2015 proton-proton data taking at a center-of-mass energy of 13 TeV and an LHC bunch-crossing interval of 50 ns. These triggers comprise of hardware-based first-level and software-based high-level trigger selections, for details see ATLAS-CONF-2012-048. In the first-level trigger, on top of a minimum pseudorapidity dependent transverse energy requirement of about 18 GeV (20 GeV) for the (lh)medium ((lh)tight) triggers, a transverse energy (ET) dependent veto on the energy deposited in the hadronic calorimeter behind the electromagnetic energy cluster is applied. For the (lh)tight triggers, a requirement on the energy deposited in the electromagnetic calorimeter in a ring around the electron cluster candidate is also added. In the high-level trigger, an ET threshold of 24 GeV is required in addition to either a cut-based (medium or tight) or a likelihood (lhmedium or lhtight) identification of the electron candidate. A requirement on the relative track isolation within a cone of R=0.2 is also applied, pTiso / ET < 0.1.

Highly ionising particle trigger performance measurements using 2012 ATLAS data ATL-COM-DAQ-2015-089 (July 08, 2015)

https://cds.cern.ch/record/2032285

The highly ionising particle (HIP) trigger is seeded by a Level-1 electromagnetic trigger with an ET threshold of 18 GeV and a veto on candidates that deposit more than 1 GeV in the hadronic calorimeter. A wedge in phi of 20 bins of 0.01 radians is built around the TRT hits associated with the Region of Interest (RoI). The bin with the maximum number of high threshold (HT) TRT hits along with its adjacent bins is used to compute the number and fraction of HT TRT hits with respect to the total number of TRT hits. The number of TRT hits is shown in a typical Drell-Yan monopole signal sample as a function of pile-up (mu), where mu is the average number of interactions per bunch crossing. At higher mu there are more low pT candidates in the event that produce a larger number of low threshold (LT) TRT hits. The number of HT hits originate primarily from the monopole traversing through the detector and it remains approximately constant.	[png] [eps] [pdf]
The fraction of high threshold TRT hits computed in a wedge in phi of size +/-0.015 centered around the bin with the highest number of HT hits in the TRT. A cut is placed on this variable at 0.37 to optimise for high signal efficiency and low rate. In data, the HIP trigger fires on dijet events that rarely produce large number of HT hits in the TRT but have large cross-sections. A typical Drell-Yan monopole signal sample produces high fraction values. The histograms are normalised to an integral of 1.	[png] [eps] [pdf]
The rate of the HIP trigger during a typical run in 2012. The plot shows the rate of the HIP trigger as a function of instantaneous luminosity of the run. At higher luminosities (corresponding to the beginning of the run) the pile-up (mu) is high and a large number of low pT candidates contaminate the wedge with low threshold hits, thereby reducing the fraction variable of the trigger. As the run progresses and the luminosity decreases, the number of low threshold hits in the wedge also decreases, hence raising the value of the fraction variable and increasing the rate. The overall rate of the trigger during all runs was less than 1 Hz.	[png] [eps] [pdf]
The trigger efficiency for a single particle monopole of mass 1000 GeV, charge 2 gD for the HIP trigger and a standard photon trigger in the barrel of the ATLAS detector. The HIP trigger is capable of firing on lower energy candidates compared to standard triggers, thereby increasing the acceptance for high charge monopoles considerably. The gain in acceptance is due to the low energy threshold of the HIP trigger and its ability to trigger on candidates that stop in the presampler and first layer of the electromagnetic calorimeter.

Electron and photon trigger performance measurements using 2012 ATLAS data ATL-COM-DAQ-2014-058 (June 27, 2014)

https://cds.cern.ch/record/1706278

Figure 1a: Output rates of the primary electron triggers of the ATLAS experiment as a function of the instantaneous luminosity during the 2012 proton-proton data taking at a center-of-mass energy of 8 TeV and an LHC bunch-crossing interval of 50 ns. These triggers comprise of hardware-based first-level and software-based high-level trigger selections, for details see ATLAS-CONF-2012-048. Different trigger transverse energy (ET) thresholds (denoted in GeV by the numbers that follow the leading “e” and “g” in the trigger names for electron and photon triggers respectively) and identification criteria (loose or medium requirements) are considered which result in different levels of purity (i.e. fraction of real electrons or photons) in the selected sample. For the single electron triggers, the hardware-based first-level trigger ET threshold varies slightly (≦2 GeV) as a function of pseudorapidity to compensate for passive material in front of the calorimeter (denoted by “v” in the trigger name), and an upper cut on the energy deposited in the hadronic calorimeter behind the electron candidate’s electromagnetic cluster is applied at the hardware level (denoted by “h” in the trigger name). For the the lowest-threshold unprescaled single electron trigger (e24vhi_medium1), a requirement on the relative track isolation within a cone of R=0.2 is applied, pT^iso / ET < 0.1 (denoted by “i” in the trigger name). For the dielectron trigger (2e12Tvh_loose1), the high-level trigger ET threshold lies in the region affected by the first-level ET cut turn-on (denoted by “T” in the trigger name). The curves show a linear increase of the rates as a function of the instantaneous luminosity, as expected. Lower thresholds and looser identification requirements accumulate higher rates from real and fake electrons or photons in the detector. A small non-linear effect is present at the highest luminosities which is related to the saturation of the Data Acquisition System and the subdetector readouts. For details on electron and photon identification in ATLAS see ATLAS-CONF-2014-032 and ATLAS-CONF-2012-123 respectively. The plotted points represent the mean rate at a given instantaneous luminosity, while the uncertainties are calculated as the RMS of the rate values in a given luminosity bin.	[png] [eps] [pdf] [jpg]

Different trigger transverse energy (ET) thresholds (denoted in GeV by the numbers that follow the leading “e” and “g” in the trigger names for electron and photon triggers respectively) and identification criteria (loose or medium requirements) are considered which result in different levels of purity (i.e. fraction of real electrons or photons) in the selected sample. For the single electron triggers, the hardware-based first-level trigger ET threshold varies slightly (≦2 GeV) as a function of pseudorapidity to compensate for passive material in front of the calorimeter (denoted by “v” in the trigger name), and an upper cut on the energy deposited in the hadronic calorimeter behind the electron candidate’s electromagnetic cluster is applied at the hardware level (denoted by “h” in the trigger name). For the the lowest-threshold unprescaled single electron trigger (e24vhi_medium1), a requirement on the relative track isolation within a cone of R=0.2 is applied, pT^iso / ET < 0.1 (denoted by “i” in the trigger name). For the dielectron trigger (2e12Tvh_loose1), the high-level trigger ET threshold lies in the region affected by the first-level ET cut turn-on (denoted by “T” in the trigger name). The curves show a linear increase of the rates as a function of the instantaneous luminosity, as expected. Lower thresholds and looser identification requirements accumulate higher rates from real and fake electrons or photons in the detector. A small non-linear effect is present at the highest luminosities which is related to the saturation of the Data Acquisition System and the subdetector readouts. For details on electron and photon identification in ATLAS see ATLAS-CONF-2014-032 and ATLAS-CONF-2012-123 respectively. The plotted points represent the mean rate at a given instantaneous luminosity, while the uncertainties are calculated as the RMS of the rate values in a given luminosity bin.	[png] [eps] [pdf] [jpg]
Figure 2a: The output rate as a function of the electron transverse energy threshold at an instantaneous luminosity of 7∙10^33 cm^-2 s^-1 during the 2012 proton-proton data taking at a center-of-mass energy of 8 TeV by the ATLAS detector with an LHC bunch-crossing interval of 50 ns. The rate is measured starting from the lowest-threshold unprescaled electron trigger with a transverse energy threshold of 24 GeV that requires medium criteria for electron identification and a relative track isolation within a cone of R=0.2, pT^iso / ET < 0.1 (e24vhi_medium1). The expected rate of electrons originating from W-->eν and Z-->ee production, scaled to the data luminosity, is shown as stacked histograms. This allows to estimate the contribution of prompt electrons originating from W and Z production at about 40-50% of the collected sample after the trigger selection. The medium identification selection in the trigger places requirements on the calorimeter shower shapes, the reconstructed track quality as well as matching requirements between the energy deposit in the calorimeter and the measured track and electron identification information provided by the Transition Radiation Tracker. These requirements are somewhat looser than the corresponding offline analysis selections that are discussed in ATLAS-CONF-2014-032.	[png] [eps] [pdf] [jpg]

The contribution is calculated as the stacked ratios of the expected number of prompt electrons from vector boson production predicted by MC simulation scaled to the data luminosity and the observed number of electron candidates in data, both after the trigger selection. This allows to estimate the contribution of prompt electrons originating from W and Z production at about 40-50% of the collected sample after the trigger selection. The medium identification selection in the trigger places requirements on the calorimeter shower shapes, the reconstructed track quality as well as matching requirements between the energy deposit in the calorimeter and the measured track and electron identification information provided by the Transition Radiation Tracker.

Figure 3a : Efficiency of photon triggers requiring a transverse energy (ET) greater than 25 GeV (open circles) and 35 GeV (open triangles) and loose photon identification criteria with respect to photons reconstructed offline passing the tight identification selection as a function of the offline photon transverse energy for \|η\|<2.37 excluding the transition region between the barrel and endcap electromagnetic calorimeters at 1.37<\|η\|<1.56 for the g25_loose (g35_loose) trigger. The loose and tight identification selections (for details see ATLAS-CONF-2012-123) apply requirements on the calorimeter shower shape variables to increase the photon purity of the selected sample. The efficiency is measured using a clean sample of radiative Z decays (Z --> ll𝛾) in the proton-proton collision data collected by the ATLAS experiment at a center-of-mass energy of 8 TeV with an LHC bunch-crossing interval of 50 ns in 2012. The sharpness of the efficiency turn-on above the trigger threshold is demonstrated on the left, while the losses as a function of the pseudorapidity are visible on the right. For offline tight photons with ET greater than the trigger threshold by at least 5 GeV, the trigger efficiency is above 99.5% for both triggers. The shown error bars are dominated by the statistical uncertainty which is calculated using a Bayesian estimate with Jeffrey’s prior.	[png] [eps] [pdf] [jpg]

Electron and photon trigger efficiencies for the early 2012 data with 4.1 fb-1 of data ATL-COM-DAQ-2012-146 (June 27, 2012)

http://cdsweb.cern.ch/record/1456795

L1, L2 and EF trigger efficiencies as a function of the offline-reconstructed electron transverse energy ET for the single electron triggers used to select medium and high ET electrons for ATLAS physics analyses: e24vhi_medium1 OR e60_medium1. These triggers apply an EF threshold on the cluster ET at 24 and 60 GeV, respectively. The identification selection of e24vhi_medium1 is more stringent than for e60_medium1, as the first applies a relative track isolation at EF, an additional selection on the longitudinal shower shape in the electro-magnetic calorimeter at EF, and an absolute hadronic leakage requirement at L1. These two triggers are combined with a logical ‘OR’ to improve the high ET efficiency, as visible in the plot in the abrupt increase in efficiency at 60 GeV. The events were collected by ATLAS in p-p collisions at the LHC, at the centre of mass energy of 8 TeV, corresponding to an integrated luminosity of 4.1 fb-1, since May 2012, after a re-optimization of the L2 and EF shower selection at high . The efficiencies are measured by applying the Zee tag-and-probe method, and are with respect to mediumPP offline electron identification, which is equivalent to the medium1 used at trigger level. The offline electron is required to have ET > 25 GeV and \|η\| < 2.47, excluding the crack regions \|η\| = 1.37-1.52. No isolation requirement is applied to the offline electron. The uncertainties are statistical and systematic.	[png] [eps] [Linear Scael png] [Linear Scale eps]

2011 Data @ 7 TeV

Electron and photon trigger efficiencies for the early 2011 data ATLAS-COM-DAQ-2011-032 (May 27, 2011)

http://cdsweb.cern.ch/record/1351827

Efficiencies for e20_medium at each trigger level (L1, L2 and EF) measured with Z->ee events using the tag-and-probe method. Efficiencies are measured as a function of the offline electron ET for candidates satisfying the tight identification requirements. The offline electrons must also be in the region \|η\|<2.47 and not coming from the transition region between the barrel and endcap part of the electromagnetic calorimeter. Opposite sign electron pairs with 80<Mee<100 GeV are used for the Z->ee selection. Data corresponding to an integrated luminosity of 206 pb-1 were used. (only statistical uncertainties are shown)	[png] [eps]

Efficiencies are measured as a function of the offline photon ET for candidates satisfying the tight identification criteria and the isolation requirement. The offline photons must also be in the region \|η\|<2.37 and not coming from the transition region between the barrel and endcap part of the electromagnetic calorimeter. The same selection criteria is used for both the tagged and probed photon and the invariant mass of the photon pairs are required to be 87<Mγγ<95. Data corresponding to an integrated luminosity of 209 pb-1 were used. (Only statistical uncertainties are shown in the plot).	[png] [eps]
