Search for t[bar over t]H Production in the All-Jet Final State in Proton-Proton Collisions at √s = 13 TeV
A search is presented for the associated production of a Higgs boson with a top quark pair in the all-jet final state. Events containing seven or more jets are selected from a sample of proton-proton collisions at √s = 13 TeV collected with the CMS detector at the LHC in 2016, corresponding to an i...

description | A search is presented for the associated production of a Higgs boson with a
top quark pair in the all-jet final state. Events containing seven or more jets are selected from a sample of proton-proton collisions at √s = 13 TeV collected with the CMS detector at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb[superscript −1]. To separate the t[bar over t]H signal from the irreducible t[bar over t] + b[bar over b] background, the analysis assigns leading order matrix element signal and background probability densities to each event. A likelihood-ratio statistic based on these probability densities is used to extract the signal. The results are provided in terms of an observed ttH signal strength relative to the standard model
production cross section µ = σ/σ[subscript SM], assuming a Higgs boson mass of 125 GeV. The best fit value is [ˆ over µ] = 0.9 ± 0.7(stat) ± 1.3(syst) = 0.9 ± 1.5 (tot), and the observed and expected upper limits are, respectively, µ < 3.8 and < 3.1 at 95% confidence levels.
