Time-integrated measurements of $\gamma$ at the Tevatron and prospects

Abstract

The measurement of CP-violating asymmetries and branching ratios of $B \to DK$ modes allows a theoretically-clean extraction of the CKM angle $\gamma$. We report recent CDF measurements with Cabibbo suppressed ($\pi\pi$, $KK$) or doubly Cabibbo suppressed ($K^+ \pi^-$) $D$ decays. These measurements are performed for the first time in hadron collisions.
