Abstract
Within the ATLAS Higgs boson working group (HWW), a study of events with two electrons and two muons in the H → WW → lνlν decay channel at 13 TeV in the ATLAS experiment at the LHC is performed. The analysis uses complete data sample accumulated during 2015–2018 exposures which corresponds to integrated luminosity 139 fb−1. Based on MC simulations, selection criteria for signal events as well as for control kinematical region for main Drell–Yan background are suggested. Expected upper limits on the heavy Higgs boson production cross section are calculated in the framework of several models. It turned out that they are only a bit worse than those obtained from the analysis of events with one electron and one muon for the H → WW → lνlν decay channel.
