| Abstract: A search is conducted for boosted Higgs bosons decaying to bottom quark pairs in association with a hadronically decaying W or Z boson at the LHC (VH). The result is based on a dataset of proton-proton collisions with a center-of-mass energy of 13 TeV collected with the CMS detector from 2016 to 2018, corresponding to an integrated luminosity of 138 fb$^{-1}$. The boson decays are reconstructed using large-radius jets and identified using heavy-flavor classifiers based on a Graph Convolutional Neural Network. Dominant backgrounds are estimated using data-driven techniques, and the signal strength for the process is obtained from a likelihood fit to the jet mass distribution of Higgs boson candidates. The same analysis strategy is applied to the associated production of a vector boson decaying into a pair of bottom quarks alongside a hadronically decaying Z boson (VZ) to validate the methodology. The observed signal strengths relative to the standard model expectation are $ \mu_{VH}= $ 0.72 $ ^{+0.75}_{-0.71} $ and $ \mu_{VZ}= $ 0.09 $ ^{+0.63}_{-0.63} $. | ||
