Topic: Implications of beyond-standard-model CP violation: electric dipole moment (EDM) tests and the collider phenomenology

Speaker: Ning Chen (USTB)

Abstract:

In this talk, I will discuss the CP violation (CPV) phenomena beyond the Standard Model (BSM). I will review the CP violation in the Standard Model, which is from the Dirac phase of the three-generational quark mixing. The experimental test was from the Kaon mixings. The BSM CPV was motivated to explain the observed puzzle of the baryon asymmetry in the Universe. It was found that the CPV in the SM is not sufficient to account for such asymmetry. Additional CPV source can be introduced by introducing a second Higgs doublet, which was motivated by T. D. Lee in `73. The indirect tests of the model are going on by measuring the electric dipole moment (EDM). I will discuss some cancellation mechanism we found in estimating the EDMs. I will also discuss some collider phenomenology in this type of model, including the diphoton searches and the Higgs pair searches at the LHC.
