Precision measurements of the τ-identification efficiency of CMS — •Olha Lavoryk, Sebastian Brommer, Maximilian Burkart, Roger Wolf, Markus Klute, and Günter Quast — Karlsruhe Institute of Technology(ETP), Karlsruhe, Germany

τ-leptons play an important role in Higgs physics because the scalar coupling to the fermions is proportional to their mass. Standard model (SM) as well as Beyond the SM (BSM) analyses require precise reconstruction of the hadronic τ-lepton decays. Discriminators based on Deep Neural Networks (DNN) provide a fast and efficient solution to this task.

In this talk, precision measurements of the τ-identification efficiency on the ultra-legacy Run-2 data taken from 2016–2018 are presented, and an appropriate uncertainty model for future Run-2+Run-3 measurements with τ-leptons in the final state is presented.
