چکیده

The mixing induced time dependent CP asymmetry, direct CP asymmetry, and branching ratio in B → ΦK S in a model III 2HDM are calculated, in particular, neutral Higgs boson contributions are included. It is shown that satisfying all the relevant experimental constraints, for time dependent CP asymmetry S φK the model III can agree with the present data, S φk = −0.39±0.41, within the 1σ error, and the direct CP asymmetry which is zero in SM can be about −8% ∼ −20% in the reasonable regions of parameters.

We describe the role of CP violation in the generation of the baryon asymmetry of the Universe, in the framework of baryogenesis through leptogenesis, with emphasis on the possible relationship between CP violation at low energies and that required by leptogen-esis. It is emphasized that a direct link between these two manifestations of CP violation only exists in the framework of specific flav...

A self-consistent analysis of K → 2π and K → 3π decays within a unique framework of chiral dynamics applied to the QCD-corrected weak nonleptonic quark lagrangian has been performed. The results on K → 2π amplitudes at O(p), including the value for ε ′ /ε, are compared with experiment to fix phenomenological B-factors for mesonic matrix elements of nonpenguin and penguin four-quark operators. T...
