简介
The rate for Higgs () bosons production in association with either one () or two () top quarks is measured in final states containing multiple electrons, muons, or tau leptons decaying to hadrons and a neutrino, using proton–proton collisions recorded at a center-of-mass energy of by the CMS experiment. The analyzed data correspond to an integrated luminosity of 137. The analysis is aimed at events that contain , , or decays and each of the top quark(s) decays either to lepton+jets or all-jet channels. Sensitivity to signal is maximized by including ten signatures in the analysis, depending on the lepton multiplicity. The separation among , , and the backgrounds is enhanced through machine-learning techniques and matrix-element methods. The measured production rates for the and signals correspond to and of their respective standard model (SM …
