Tau trigger performance plots on 2017 data ( CMS DP-2018/009)

The trigger efficiency is estimated using Tag and Probe (TnP) method in Z to μtauh events. The trigger efficiency is calculated with the ratio of the events which pass the baseline TnP selection as well as the given HLT path and the events which pass only the TnP selection. The trigger efficiencies are measured in the full 2017 dataset corresponding to an integrated luminosity of 41.5 fb−1 and compared to a Drell-Yan simulation. The data-taking of 2017 experienced three different main phases due to the changes in the condition of the pixel detector. The first weeks of the data-taking (Era 2017B with 4.8 fb−1) was dedicated to the commissioning of the new pixel detector and some dead pixel modules had been observed. The middle phase (Era 2017C-E with 23.1 fb−1) was quite stable after the deployment of tracking mitigation strategies. The last weeks of the data-taking (Era 2017F with 13.6 fb−1) experienced additional technical issues with the pixel detector resulting in a loss of trigger efficiency.

μ tauh trigger efficiency versus pT of the tau
(HLT_IsoMu20_eta2p1_LooseChargedIsoPFTau27_eta2p1_CrossL1)
The hadronic tau leg efficiency of μtauh triggers (given above) is shown on the right as a function of offline tau pT. The shown efficiency corresponds to the combined L1 and HLT efficiency. The μ tau cross trigger, used for H in tautau analysis, has loose isolation and pT (tau)> 27 GeV, seeded by a μ + tau L1 trigger seed.

e tauh trigger efficiency versus pT of the tau
(HLT_Ele24_eta2p1_WPTight_Gsf_LooseChargedIsoPFTau30_eta2p1_CrossL1)
The tauh-leg efficiency of etauh trigger is measured by using the following μ tau trigger: HLT_IsoMu20_eta2p1_LooseChargedIsoPFTau27_eta2p1_CrossL1. The combined L1 and HLT efficiency of the tau-leg of the μ tau trigger is shown. The μ taucross trigger has loose isolation and pT(tau) > 27 GeV. In addition, the tighter online selections applied in the e tau trigger are required in the μ tau trigger.

A combination of several μtau trigger paths with different isolation and ID requirement is used, with pT thresholds down to 35 GeV (given above). The combination improves the trigger efficiency. The combined L1 and HLT efficiency of the tauh-leg is shown [Get pdf version]

μ tauh trigger efficiency versus eta

The combined L1+HLT efficiency is shown as a function of eta. In addition to the previous cuts, an offline cut on the tau pT is applied to be above the trigger threshold: pT > 32 GeV. The efficiency is here shown for the different data-taking periods. The 2017B era suffered from pixel inefficiencies affecting in particular the regions 0 < eta < 1.48 & phi > 2.8; −1.48 < eta < 0 and phi < −2.8. From the 2017C era, the track reconstruction in the trigger has been updated to recover some efficiency in those regions. During the 2017F era, additional pixel issues reduced the overall efficiency and more importantly in the region 0 < eta < 2.1 and 1.6 < phi < 2 .
