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 from about eight to twenty percents in the reasonable regions of parameters.

I review the phenomenology of new physics in low energy processes using the notion of minimal flavor violation (vs. non-minimal flavor violation). I compare the predictions of beyond-the-standard models and show that among certain observables in rare b-decays pattern arise, which allow to distinguish between extensions of the Standard Model. I discuss the status and future of the model independ...

We obtain tree-level unitarity constraints for the most general Two Higgs Doublet Model (2HDM) with explicit CP-violation. We briefly discuss correspondence between possible violation of tree level unitarity limitation and physical content of the theory. The Electroweak Symmetry Breaking in the Standard Model is described usually with the Higgs mechanism. In its simplest variant, an initial Hig...
