HPS based and Cone based tau reconstruction comparison (mu-tauh trigger) HPS tau reconstruction was deployed at HLT in the beginning of 2018 data-taking. The efficiency of hadronic tau leg of the mu-tau trigger is shown as a function of offline tau pT for the 17.7 fb-1 data taken with the cone-based tau reconstruction and for 42.0 fb-1 data collected with the HPS-based algorithm in 2018. The combined L1 and HLT efficiency of the tauh-leg is shown. The HPS-based tauh reconstruction algorithm has a rate of 4.6 Hz for mu-tau trigger at average PU = 50, while the rate for cone-based algorithm was 5.2 Hz for mu-tau trigger. So, the HPS reduces the rate by 10% for mu-tau trigger [Ref: CMS DP -2018/035]. Caption [Get pdf version] Contact: Hale Sert

pT resolution of HPS-based and cone-based tau reconstruction pT resolution of the HPS based and cone-based tau reconstruction is shown on the right. The resolution is calculated for mu-tauh trigger by comparing pT of the online and offline tau leptons. It is calculated using the first 17.7 fb-1 of data taken with the cone-based tau reconstruction, where the trigger paths with HPS based algorithm was included for the purpose of testing. The HPS-based tauh reconstruction has better pT resolution compared to the cone-based reconstruction. Caption [Get pdf version] Contact: Hale Sert
