Description
Summary:This Letter presents the first study of Higgs boson production in association with a vector boson (๐‘‰ =๐‘Š or ๐‘) in the fully hadronic ๐‘žโข๐‘žโข๐‘โข๐‘ final state using data recorded by the ATLAS detector at the LHC in proton-proton collisions at โˆš๐‘ =13 TeV and corresponding to an integrated luminosity of 137 fbโˆ’1. The vector bosons and Higgs bosons are each reconstructed as large-radius jets and tagged using jet substructure techniques. Dedicated tagging algorithms exploiting ๐‘-tagging properties are used to identify jets consistent with Higgs bosons decaying into ๐‘โขยฏ๐‘. Dominant backgrounds from multijet production are determined directly from the data, and a likelihood fit to the jet mass distribution of Higgs boson candidates is used to extract the number of signal events. The ๐‘‰โข๐ป production cross section is measured inclusively and differentially in several ranges of Higgs boson transverse momentum: 250-450, 450-650, and greater than 650 GeV. The inclusive signal yield relative to the standard model expectation is observed to be ๐œ‡=1.4+1.0โˆ’0.9 and the corresponding cross section is 3.1ยฑ1.3โข(stat)+1.8โˆ’1.4โข(syst) pb.
