First reconstruction of suppressed $B^- \to D(K^+\pi^-)K^-$ and $B^- \to D(K^+\pi^-)\pi^-$ decays in hadron collisions

Demonstrates the maturity of hadron collider experiments in studying B decays

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 $B^0_s \to pi^+\pi^-$, and the first reconstruction in hadron collisions of the suppressed decays $B^- \to D(\to K^+\pi^-)K^-$ and $B^- \to D(\to K^+\pi^-)\pi^-$.
