Search for the supersymmetric tau lepton using Run2 data of the CMS experiment — •Leonid Didukh, Isabell Melzer-Pellmann, and Dirk Krücker — Deutsches Elektronen Synchrotron (DESY), Hamburg, Deutschland

Supersymmetry is a popular theory of new physics beyond the Standard Model. Particularly searches for the supersymmetric partner of the tau lepton τ still remain a promising approach, since the τ pair production has a very small cross-section that can be probed with the full Run2 luminosity.

This talk contains the status of the search for direct stau production using data collected by the CMS Collaboration at the CERN LHC during 2016-2018 at a center-of-mass-energy of 13TeV. The presented analysis is based on a final state with missing energy and two taus, one hadronically decaying tau and one electron or muon produced from the second tau decay. Unlike the previous analysis that contains data from 2016-2017, this analysis explores more MVA tools and will show how these models (DNN, BDT, combined models architectures for heterogeneous tabular data) can significantly improve the results.
