+ | | ||

+ | | ||

+ | | ||

+ | | ||

+ | decay amplitudes by defining ``tree'' | ||

+ | | ||

+ | angle $\gamma$. We propose strategies to obtain insights into the dynamics | ||

+ | of penguin processes with the help of the decays $B_{u,d}\to K\overline{K}$ | ||

+ | and $B^\pm\to\pi^\pm K$, derive a relation among the direct CP-violating | ||
