Seminarium Fizyki Wielkich Energii

Violation of the CP symmetry is one of the Sakharov conditions required to explain the baryon asymmetry observed in Universe. Although the CP violation is already built in the Standard Model via quark mixing, its strength is not sufficient to explain the magnitude of the observed baryon asymmetry. This motivates searches for new sources of CP violation in the Higgs sector. In this seminar recent results of studies on the CP structure of the Higgs boson coupligs with the CMS experiment will be discussed.
