| Abstract: A search is conducted for Higgs bosons produced with high transverse momentum ($ p_{\mathrm{T}} > $ 450 GeV) via vector boson fusion at the LHC proton-proton collider operating at center of mass energy $ \sqrt{s}= $ 13 TeV. The result is based on the 138 fb$ ^{-1} $ data set collected by the CMS detector in 2016, 2017, and 2018. The decay of a high-$ p_{\mathrm{T}} $ Higgs boson to a boosted bottom quark-antiquark pair is isolated by selecting large-radius jets and exploiting jet substructure and heavy flavour taggers based on advanced machine learning techniques. Independent regions targeting vector boson fusion and gluon-gluon fusion are defined based on the topology of forward quark jets. The signal strengths for both processes are extracted simultaneously by performing a maximum likelihood fit to data in the large-radius jet mass distribution. The observed signal strengths are 2.1$ ^{+1.9}_{-1.7} $ and 5.0$ ^{+2.1}_{-1.8} $ for gluon-gluon fusion and vector boson fusion, respectively. | ||
