Weak phase information from the color suppressed B_d^0 -> D^{*0} K^{*0} modes

Abstract

The decay channels $B_d^0\to D^{\ast 0}{K}^{\ast 0}$ are investigated for extracting weak $CKM$ phase information. These channels are described by color-suppressed tree diagrams only and are free from penguin contributions. The branching ratios for these channels are found to be $\sim \mathcal{O}$ $(10^{-5}-10^{-6})$ which can be measured at the currently running $B$ factories. The method presented here may be well-suited to determine the phase $\gamma$.
