Measuring $\gamma$ in $B^{\pm }\to K^{\pm }(K{K}^{\ast }{)}_D$ decays

Abstract

We develop a method to measure the CKM angle $\gamma$ without hadronic uncertainties from the analysis of $B^{\pm }\to K^{\pm }{D}^0$ and $K^\pm \D0bar$ followed by singly Cabibbo-suppressed $D$ decays to non CP-eigenstates, such as $K^{\pm }{K}^{\ast \mp }$. This method utilizes the interference between $b\to c\bar{u}s$ and $b\to u\bar{c}s$ decays, and we point out several attractive features of it. All the modes that need to be measured for this method are accessible in the present data.
