Measurement of the associated production of a top-antitop-quark pair and a Higgs boson decaying into a b(b)over-bar pair in pp collisions at √s=13 TeV using the ATLAS detector at the LHC

Popis výsledku v původním jazyce

This paper reports the measurement of Higgs boson production in association with a t (t) over bar pair in the H -&gt; b (b) over bar decay channel. The analysis uses 140 fb(-1) of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. The final states with one or two electrons or muons are employed. An excess of events over the expected background is found with an observed (expected) significance of 4.6 (5.4) standard deviations. The t (t) over barH cross-section is sigma(t (t) over barH)=411(-92)(+101)fb=411 +/- 54(stat.)(-75)(+85)(syst.)fb for a Higgs boson mass of 125.09 GeV, consistent with the prediction of the Standard Model of 507(-50)(+35) fb. The cross-section is also measured differentially in bins of the Higgs boson transverse momentum within the simplified template cross-section framework.
