$B\rightarrow h^+h^-$ results from 360pb$^{-1}$ at CDF

We report an update of the analysis of $B^0_(s)\rightarrow h^+h'^-$ decays (where h and h$'$ denote K or pi) with 360 pb$^{-1}$ of proton-antiproton collisions at $\sqrt(s)$=1.96 TeV, with the CDF II detector at the Tevatron Collider. The results include a measurement of direct CP-violating asymmetry between $B^0\rightarrow K^+pi^-$ and $\bar{B^0}\rightarrow K^-\pi^+$ decay-rates at the 4\% level, based on a sample of about 1600 events.
