Search for a boosted Higgs boson decaying to bottom quark pairs in association with a W or Z boson in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Abstract

A search is conducted for standard model Higgs bosons with large transverse momentum ($p_{\mathrm{T}}$) decaying to bottom quark pairs and produced in association with a hadronically decaying W or Z boson at the LHC. The result is based on a dataset of proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector in 2016$-$2018, corresponding to an integrated luminosity of 138 fb${}^{-1}$. Boosted Higgs, W, and Z boson decays are reconstructed using large-radius jets with $p_{\mathrm{T}}$ $>$ 450 GeV and identified with heavy-flavor classifiers based on a graph convolutional neural network. The observed signal strength relative to the standard model expectation is $\mu$ = 0.72 ${}_{-0.71}^{+0.75}$ including statistical and systematic uncertainties.
