Description
A search for Higgs boson pair production in bbll+MET final state with the ATLAS experiment will be presented. The analysis uses the full Run~2 data-set (139fb−1) collected at the LHC in pp collisions at √s=13TeV. Di-Higgs boson production from the SM tri-Higgs-boson interaction and from BSM resonant decays are investigated with a final state containing two jets (one or two tagged as b-jets) and two leptons with opposite electric charge. Three different channels where one of the Higgs bosons decays via H→bb and the other via H→WW∗/ZZ∗/τ+τ− are included as di-Higgs signals contributions in the analysis. A deep-learning neural network has been used for event selection to improve the ATLAS di-Higgs boson detection sensitivity. The expected upper limits on the cross-sections were investigated based on MC simulated events.
