Study of misidentified of hadronic tau lepton using fakefactor method


This paper describes a algorithm to identify the visible decay products of hadronic tau decays (τhad-vis) in the Standard Model Higgs boson produced in association with a top quark pair in multilepton final states with two light leptons with same-sign electric charges and one hadronically decaying tau lepton, labeled as 2LSS1τhad at √s=13 TeV. The algorithm is based on recurrent neural networks (RNN) employing information from reconstructed charged-particle tracks and clusters of energy in the calorimeter associated to τ had-vis candidates as well as high-level discriminating variables. The expected performance of this algorithm is evaluated in simulated proton–proton collisions at √s=13 TeV and compared to a BDT-based approach.

Keywords: Fake Factor method, Hadronic τ lepton, RNN, traces of charged particles
