Abstract
Authors within the Higgs Boson Working Group (HWW) of the ATLAS experiment at the LHC performed an analysis of events with electron, muon and two hadron jets to study Standard Model Higgs boson properties in the h → WW* → еνμν decay channel. The analysis is based on full statistics of proton-proton interactions taken during 2015–2018 year exposures at 13 TeV energy in their rest-frame. With respect to our previous analysis, the data sample used is four times larger, the reconstruction software as well as signal and background samples are updated. Exposures taken at high LHC luminosity are studied separately. It turned out that most of experimental spectra for hadron jets at early selection stages in the signal region are rather well modeled by Monte-Carlo simulations. Even at high luminosity, there are no serious problems with forward going hadron jets reconstruction. Kinematic distributions in the control regions of main backgrounds are reproduced by the Monte-Carlo.
