Fake-Rate Determination for the ttH and ttW Production with a Signature of Two Same Electric Charge Light Leptons Associated with a Tau Using the ATLAS Detector at the LHC — •Santu Mondal¹, Babar Ali¹, Simonetta Gentile², Nazim Huseynov³, Antonio Policicchio², and Andre Sopczak¹ — ¹IEAP CTU in Prague — ²Universita di Roma Sapienza — ³JINR Dubna

After the discovery of a Higgs boson, the measurements of its properties are at the forefront of research. The determination of the associated production of a Higgs boson and a pair of top quarks is of particular importance as the ttH Yukawa coupling is large and can probe for physics beyond the Standard Model. The analysis is based on data taken by the ATLAS experiment recorded from 13 TeV proton-proton collisions. The ttH and ttW production was analysed in various final states. The focus of this presentation is on the fake rate determination in the final state with two light leptons of same electric charge and one hadronically decaying tau lepton.
