Abstract

A search is conducted for standard model Higgs bosons with large transverse momentum ( p 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 TeVcollected with the CMS detector in 2016–2018, corresponding to an integrated luminosity of 138fb−1. Boosted Higgs, W, and Z boson decays are reconstructed using large-radius jets with p 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 μ=0.72−0.71+0.75 including statistical and systematic uncertainties.
