An inclusive search for the standard model Higgs boson (H) produced with large transverse momentum (pT) and decaying to a bottom quark-antiquark pair (bb) is performed using a data set of pp collisions at √(s)=13 TeV collected with the CMS experiment at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb^\ensuremath-1. A highly Lorentz-boosted Higgs boson decaying to bb is reconstructed as a single, large radius jet, and it is identified using jet substructure and dedicated b tagging techniques. The method is validated with Z\ensuremath→bb decays. The Z\ensuremath→bb process is observed for the first time in the single-jet topology with a local significance of 5.1 standard deviations (5.8 expected). For a Higgs boson mass of 125 GeV, an excess of events above the expected background is observed (expected) with a local significance of 1.5 (0.7) standard deviations. The measured cross section times branching fraction for production via gluon fusion of H\ensuremath→bb with reconstructed pT>450 GeV and in the pseudorapidity range \ensuremath-2.5<\ensuremathη<2.5 is 74\ifmmode±\else\textpm\fi48(stat)_\ensuremath-10+17(syst) fb, which is consistent within uncertainties with the standard model prediction.
