Abstract
A study of events with two opposite-sign electrons and muons in the final state to search for Standard Model Higgs boson and heavy resonance in the decay channel to two W-bosons is performed in the ATLAS experiment at the LHC. Authors within the HWW group performed an analysis of events using full statistics of pp-collisions recorded during 2015–2018 year exposures at 13 TeV in their rest-frame. Thanks to a use of a deep neural network, we were able to improve significantly our previous results on the extraction of the H-boson signal in the vector-boson-fusion production mechanism. In the framework of different theoretical models new expected upper limits on a heavy resonance production cross section with spin 0, 1 and 2 were calculated in addition to those obtained earlier in the NWA toy model for a heavy Higgs boson.
