Search for supersymmetry with tau leptons in the CMS experiment using MVA approach — •Ilya Bobovnikov1, Alexis Kalogeropoulos1,2, Isabell Melzer-Pellmann1, and Alexei Raspereza1 — 1DESY — 2Princeton
Supersymmetry (SUSY) is a popular theory beyond-the-standard-model. A search for SUSY in events with τ leptons in the final state using an MVA technique with 36/fb of 13 TeV data taken during 2016 is presented. Results are interpreted in terms of a direct stau-pair production model, where each stau is expected to decay to a τ lepton and the lightest SUSY particle (LSP). To optimize the sensitivity to the direct stau-pair production topology, we apply and compare various MVA approaches with different kinematic variables, based on final states with one hadronically decaying τ lepton and an electron or muon from the decay of the second τ. Finally, expected exclusion limits are calculated and compared with a cut based approach.
