Updated measurements of hadronic B decays at CDF

Abstract

The CDF experiment at the Tevatron $p\bar{p}$ collider established that extensive and detailed exploration of the $b$--quark dynamics is possible in hadron collisions, with results competitive and supplementary to those from $e^{+}{e}^{-}$ colliders. This provides a rich, and highly rewarding program that has currently reached full maturity. In the following I report some recent results on hadronic decays: the evidence for the charmless annihilation decay mode $B_s^0\to p{i}^{+}{\pi }^{-}$, and the first reconstruction in hadron collisions of the suppressed decays $B^{-}\to D(\to K^{+}{\pi }^{-})K^{-}$ and $B^{-}\to D(\to K^{+}{\pi }^{-}){\pi }^{-}$.
