dc.description.abstract	A search for standard model Higgs bosons (H) produced with transverse momentum (pT) greater than 450 GeV and decaying to bottom quark-antiquark pairs (bb¯¯¯) is performed using proton-proton collision data collected by the CMS experiment at the LHC at s? = 13 TeV. The data sample corresponds to an integrated luminosity of 137 fb?1. The search is inclusive in the Higgs boson production mode. Highly Lorentz-boosted Higgs bosons decaying to bb¯¯¯ are reconstructed as single large-radius jets, and are identified using jet substructure and a dedicated b tagging technique based on a deep neural network. The method is validated with Z ? bb¯¯¯ decays. For a Higgs boson mass of 125 GeV, an excess of events above the background assuming no Higgs boson production is observed with a local significance of 2.5 standard deviations (?), while the expectation is 0.7. The corresponding signal strength and local significance with respect to the standard model expectation are ?H = 3.7 ± 1.2(stat)+0.8?0.7(syst)+0.8?0.5(theo) and 1.9 ?. Additionally, an unfolded differential cross section as a function of Higgs boson pT for the gluon fusion production mode is presented, assuming the other production modes occur at the expected rates.	en_US
