A measurement is performed of Higgs bosons produced with high transverse momentum (p&sub(T)) via vector boson or gluon fusion in proton-proton collisions. The result is based on a data set with a center-of-mass energy of 13 TeV collected in 2016–2018 with the CMS detector at the LHC and corresponds to an integrated luminosity of 138 fb*−*1 . The decay of a high-p&sub(T) Higgs boson to a boosted bottom quark-antiquark pair is selected using largeradius jets and employing jet substructure and heavy-favor taggers based on machine learning techniques. Independent regions targeting the vector boson and gluon fusion mechanisms are defned based on the topology of two quark-initiated jets with large pseudorapidity separation. The signal strengths for both processes are extracted simultaneously by performing a maximum likelihood ft to data in the large-radius jet mass distribution. The observed signal strengths relative to the standard model expectation are 4.9&sup(+1.9)&sub(−1.6) and 1.6&sup(+1.7)&sub(−1.5) for the vector boson and gluon fusion mechanisms, respectively. A diferential cross section measurement is also reported in the simplifed template cross section framework.
