| dc.description.abstract | A search for standard model Higgs bosons (H) produced with transverse momentum (\(p_{T}\)) greater than 450 GeV and decaying to bottom quark-antiquark pairs ( \(b\overline{b}\) ) is performed using proton-proton collision data collected by the CMS experiment at the LHC at \(\sqrt{s}\) = 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 \(b\overline{b}\) 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 → \(b\overline{b}\) 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 μ H = 3.7 ± 1.2(stat) \({}_{-0.7}^{+0.8}\) (syst) \({}_{-0.5}^{+0.8}\) (theo) and 1.9 σ. Additionally, an unfolded differential cross section as a function of Higgs boson \(p_{T}\) for the gluon fusion production mode is presented, assuming the other production modes occur at the expected rates. | en_US |
