Description
An important goal in the investigation of the Higgs boson is the determination of its CP structure. In this talk, we investigate in detail constraints on the CP nature of the Higgs-fermion-fermion couplings. We take into account all relevant collider constraints in a global fit. Starting with simple effective models featuring CP violation in only one Higgs-fermion-fermion coupling, we successively allow for CP violation in more couplings. Moreover, we study the complementarity with electric dipole measurements and assess to which extent CP violation in the Higgs-fermion-fermion coupling can account for the baryon-antibaryon asymmetry of the Universe.
