A new method for extracting the weak phase gamma from B ---> D K(*) decays

Abstract

A new method to extract the weak phase $\gamma$ is suggested by exploiting B ---> D K^{(*)} decay modes that are not Cabibbo suppressed, using the isospin relations, and ignoring the annihilation diagram as usual. Assuming $3\times 10^{8}B\bar{B}$ pair at $B$ factories, one can determine $\gamma$ with $3-\sigma$ accuracy for 80^o < $\gamma$ < 150^o using B ---> D K modes and for 50^o < $\gamma$ < 170^o using B ---> D K^* modes.
