Experimental Particle and Astro-Particle Physics Seminar

Monday 12 Apr 2021, 14:00 → 16:00 Europe/Zurich

Florencia Canelli (Universitaet Zuerich (CH))

One of the important tests of the SM is the measurement of the top quark Yukawa coupling, directly measured via the associated production process pp→tt̄H. Both ATLAS and CMS have performed searches of tt̄H targeting the most relevant Higgs decay modes in final states with high lepton multiplicity, high b-jet multiplicity, or containing two photons at √s=13 TeV. In this talk, the latest results on the search for the tt̄H process in the multilepton and multibjets final states with the ATLAS experiment will be discussed, together with a detailed study of their main background processes, tt̄W and tt̄bb̄, and unexpected tensions observed in data.
