| Abstract: A search for the standard model Higgs boson produced with high transverse momentum decaying to a bottom quark-antiquark pair has been performed using a data set of pp collisions at $\sqrt{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 high-transverse-momentum Higgs boson decaying to $\mathrm{b\bar{\mathrm{b}}}$ is reconstructed as a single jet and identified based on jet substructure and dedicated b-tagging techniques. The analysis strategy is validated with $ \mathrm{Z}\rightarrow \mathrm{b\bar{\mathrm{b}}} $ decays. The $ \mathrm{Z}\rightarrow \mathrm{b\bar{\mathrm{b}}}$ process is observed with a local significance of 5.1 standard deviations for the first time in the single jet topology. For a Higgs boson mass of 125 GeV, an excess of events is observed above the expected background with a local significance of 1.5 standard deviations. The measured cross section of $ \mathrm{H}(\mathrm{b\bar{\mathrm{b}}})$ production for ${p_\mathrm{T}}> $ 450 GeV is 74$_{-49}^{+51}$ fb. | ||

| Summary |
|
An inclusive search for the standard model Higgs boson decaying to bottom quark-antiquark pairs with $p_{\mathrm{T}} > $ 450 GeV and reconstructed as a single jet has been presented using a data sample of proton-proton collisions collected by CMS corresponding to 35.9 fb$^{-1}$ at $ \sqrt{s} = $ 13 TeV. The Higgs jets are reconstructed with the anti-$k_{\mathrm{T}}$ algorithm with radius $R= $ 0.8 and identified with the CMS double-b tag algorithm. The signal is then extracted on top of the falling QCD soft drop mass distribution (including contributions from W, Z, and top background processes) using an entirely data-driven QCD background prediction. The analysis strategy is validated by extracting the signal strength of the Z+jets process. The Z+jets process is observed for the first time in the single-jet topology with a significance of 5.1$\sigma$. The Higgs production is measured with a signal strength parameter of $\mu_\mathrm{ H }= $ 2.3$_{-{1.6} }^{+{1.8} }$ and an observed significance of 1.5$\sigma$ (0.7$\sigma$ expected for the standard model Higgs) when including Higgs $p_{\mathrm{T}}$ spectrum corrections accounting for NLO and finite top mass effects. The measured cross section of the $\mathrm{ H }(\mathrm{ b \bar{b} })$ production for $p_{\mathrm{T}} > $ 450 GeV is 74$_{-{49} }^{+{51} } $ fb, which is consistent with the SM expectation within the uncertainty. |
