| Özet |
| 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 13 TeV collected with the CMS detector at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb. To separate the H signal from the irreducible 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 H signal strength relative to the standard model production cross section , assuming a Higgs boson mass of 125 GeV. The best fit value is 0.9 0.7 (stat) 1.3 (syst) = 0.9 1.5 (tot), and the observed and expected upper limits are, respectively, 3.8 and 3.1 at 95% confidence levels. |
