内容記述タイプ | Abstract | |||||
内容記述 | We give the detailed analyses for the gluonic-penguin effect on the Kπ and ππ decays of the B meson. In the standard model, it is shown that the ratio BR(B → Kπ)/BR(B → ππ) takes the value 0.5 ∼ 3.0 with the strongly depending on the CP violating phase φ and the KM matrix element |V_<ub>|. We obtain the constraint on the form factor by using the experimental branching ratio. It is also found that, in the two-Higgs-doublet model, the charged Higgs contribution which could enhance the B → X_<sγ> decay does not a sizable effect on our processes. The effect of the final state interaction on these processes is also discussed. | |||||
