Abstract
Within the ATLAS Higgs boson working group (HWW), a study of events with two leptons in the h/H → WW(*) → lνlν decay channel in pp-collisions at 13 TeV with the ATLAS detector at the LHC is performed. The analysis uses complete data sample accumulated during 2015—2018 exposures which corresponds to integrated luminosity 139 fb−1. Particular attention was paid to study forward going hadron jet properties. Such jets accompany Higgs boson production in the vector boson fusion mechanism. A comparison of two jet reconstruction algorithms, EMTopo and PFlow, is performed. The second algorithm is chosen for further analyses as more robust to conditions at high LHC luminosity. Jet kinematics is studied separately for exposures at different differential luminosities. The first results of the analysis of control regions of main backgrounds to heavy Higgs boson based on complete 13 TeV statistics are also given.
