Nazim Huseynov "Study of the associative production of the Higgs boson with top quarks in the ATLAS experiment at the Large Hadron Collider"
The interaction of the Higgs boson with the heaviest particle of the Standard Model—the top quark—seems promising for the search for new physics beyond the Standard Model (BSM). This interaction is determined by the Yukawa coupling constant. Its complex phase remains unknown to date but can be defined by studying the process of the Higgs boson production in association with a single top quark.
The report presents the results of a search for such a process using data from proton-proton collisions with an integrated luminosity of 140 fb-1, collected at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider (LHC). The analysis focuses on final states such as H→bb,WW,ZZ,ττ, which indicate the presence of a Standard Model Higgs boson accompanied by an electron or muon from the decay of a top quark. Multivariate methods are used to separate the signal from the background, and upper limits on the cross-section of the process are established.
