Descripción
An inclusive search for the standard model Higgs boson (H ) produced
with large transverse momentum (pT ) and decaying to a bottom
quark-antiquark pair (b b ¯ ) is performed using a data set of p p
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-1 . A highly Lorentz-boosted Higgs boson decaying to b b
¯ 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 →b b ¯ decays. The Z →b b
¯ 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 →b b ¯ with reconstructed
pT>450 GeV and in the pseudorapidity range -2.5 <η
<2.5 is 74 ±48 (stat)-10+17(syst) fb ,
which is consistent within uncertainties with the standard model
prediction.
