CP violation at low energy is observed in K and B system. In the future neutrino oscillation experiments , CP asymmetry of the neutrino oscillations P (νi → νj) 6= P (ν̄i → ν̄j) may be also measured. Our question is how low energy CP violation measurements are related to CP violation for Baryon number asymmetry. Fukugita and Yanagida proposed a scenario for Baryon number asymmetry based on the se...

The Standard Model parametrization of CP violation is described. Tests of this parametrization using the observed heavy flavour decays and implications for New physics are discussed.

Measurements of CP asymmetries in B decays will soon be made at B factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle and the resulting CP asymmetries in B decays. This is done both in the standard model and in several variants of the minimal supersymmetric standard model (MSSM), which are characterized by a single phase in the quark f...

We investigate CP-violation effects in the bosonic sector of the Standard Model (SM) with two Higgs doublets. First we calculate the mass eigenstates of the physical neutral Higgses for small but nonzero CP-violation parameter ξ∗, and then a “forward-backward” asymmetry Afb for the decay H → W+W−Z that would be a signal of CP-violation. Although the effects are in general small (Afb = Γfb/Γ ∼ O...

By using the relation between CP-violation phase and the mixing angles in CabibboKobayashi-Maskawa matrix postulated by us before, the rephasing invariant is recalculated. Furthermore, the problem about maximal CP violation is discussed. We find that the maximal value of Jarlskog’s invariant is about 0.038. And it presents at α ≃ 71.00, β ≃ 90.20 and γ ≃ 18.80 in triangle db. PACS number(s): 11...
