Abstract

We present the first search for the standard model Higgs boson (H) produced with large transverse momentum (pT\mathrm{p_{T}}) via gluon fusion and decaying to a bottom quark-antiquark pair (bb\mathrm{b\overline{b}}). The search is performed using a data set of pp collisions at s=13\sqrt{s}=13 TeV collected with the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb1^{\mathrm{-1}}. A highly Lorentz-boosted Higgs boson decaying to bb\mathrm{b\overline{b}} is reconstructed as a single, large radius jet and is identified using jet substructure and dedicated b tagging techniques. The method is validated with the first observation of the Zbb\rightarrow\mathrm{b\overline{b}} process in the single-jet topology, with a local significance of 5.1 standard deviations (5.8 expected).
