A search for standard model Higgs bosons (H) produced with transverse momentum (pTT​) greater than 450 GeV and decaying to bottom quark-antiquark pairs (bb‾bb) is performed using proton-proton collision data collected by the CMS experiment at the LHC at ss ​ = 13 TeV. The data sample corresponds to an integrated luminosity of 137 fb−1−1. The search is inclusive in the Higgs boson production mode. Highly Lorentz-boosted Higgs bosons decaying to bb‾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‾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 (σ), while the expectation is 0.7. The corresponding signal strength and local significance with respect to the standard model expectation are μHH​ = 3.7 ± 1.2(stat)−0.7+0.8−0.7+0.8​(syst)−0.5+0.8−0.5+0.8​(theo) and 1.9 σ. Additionally, an unfolded differential cross section as a function of Higgs boson pTT​ for the gluon fusion production mode is presented, assuming the other production modes occur at the expected rates.[graphic not available: see fulltext]
