CP and charge asymmetries at CDF

We present CDF results on the branching fractions and time-integrated direct CP asymmetries for B0 and B0s decay modes into pairs of charmless charged hadrons (pions or kaons). We report also the first observation of B0s->DsK mode and the measurement of its branching fraction.

Branching fractions and direct CP asymmetries of charmless decay modes at the Tevatron

We present new CDF results on the branching fractions and time-integrated direct CP asymmetries for $B^{0}$ and $B^{0}_{s}$ decay modes into pairs of charmless charged hadrons (pion or kaon). The data set for this update amounts to 1 fb$^{-1}$ of $\bar{p}p$ collisions at $\sqrt{s}=1.96 \rm{TeV}$. We report the first observation of the $B^{0}_{s} \to K^{-}π^{+}$ mode and a measurement of its branching fraction and direct CP asymmetry. We also observe for the first time two charmless decays of $b$-baryon: $Λ^{0}_{b} \to pπ^{-}$ and $Λ^{0}_{b} \to pK^{-}$.
