We investigate the mass differences ∆M B d,s in the mixing B 0 d,s −B 0 d,s with a new up-like quark t ′ in a sequential fourth generation model. We give the basic formulae for ∆M B d,s in this model. (1), then, we analysis the final numerical results of ∆M Bs , which is the function of m t ′ through a fourth generation CKM factor V * t ′ s V t ′ b constrained by the rare decay B → X s l + l − and two new Wilson coefficients S 0 (x t ′ ) and S 0 (x t , x t ′ ). We found that one kind of the new results are satisfied with the present experimental low-bound of ∆M Bs . (2), we get the constraint of the fourth generation CKM factor V * t ′ b V t ′ d , (which is also the function of t ′ ), from the experimental measurements of ∆M B d and give the figs. of V * t ′ b V t ′ d to m t ′ and the general CKM factor V * tb V td . We also give the numerical results of the Wilson coefficients S 0 (x t ′ ), S 0 (x t , x t ′ ) and η t ′ , η tt ′ as the function of m t ′ . We also talk about the hierarchy of the fourth generation CKM matrix. As one of the directions beyond the SM, ∆M B d,s could provide a possible test of the fourth generation or perhaps a signal of the new physics.

Strategies for fixing the CKM-angle γ and obtaining experimental insights into the world of electroweak penguins

Using the SU(3) flavour symmetry of strong interactions, we propose strategies for extracting both the CKM-angle γ and theb →ūus tree-level amplitude T ′ . We present also an approximate approach using the branching ratios for the modeswhich should be rather promising from the experimental point of view. The quantities γ and T ′ determined this way may well be used as an input to control electroweak penguins in nonleptonic B-decays as has been discussed in previous work. Following these lines, we propose strategies for obtaining quantitative insights into the physics of the electroweak penguin operators and performing some consistency checks. As a by-product, we derive an upper bound of 6 • for the uncertainty originating from electroweak penguins in the α-determination by means of B → ππ decays.

CP violation and the CKM angle γ from angular distributions of untagged Bs decays governed by

We demonstrate that time-dependent studies of angular distributions for B s decays caused byb →cus quark-level transitions extract cleanly and model-independently the CKM angle γ. This CKM angle could be cleanly determined from untagged B s decays alone, if the lifetime difference between the B s mass eigenstates B L s and B H s is sizable. The timedependences for the relevant tagged and untagged observables are given both in a general notation and in terms of linear polarization states and should exhibit large CP-violating effects. These observables may furthermore provide insights into the hadronization dynamics of the corresponding exclusive B s decays thereby allowing tests of the factorization hypothesis.
