TThe LHCb collaboration has recently reported evidence for non-zero CP asymmetries in $B^+$ decays into $\pi^+ K^+ K^-,\; \pi^+\pi^+\pi^-,\; K^+ K^+ K^- $ and $K^+\pi^+\pi^-$. The branching ratios for these decays have also been measured…

We present Dalitz-plot analyses of $B^+\to K^+\pi^-\pi^+$ and $B^0\to K^+\pi^-\pi^0$ using the data sample collected at the $\Upsilon(4S)$ by the BABAR detector. We have found evidence for direct CP-violation in the decay $B^\pm\to\rho^0…

In the framework of QCD factorization, based on the first order of isospin violation, we study direct CP violation in the decay of $\bar{B}_{s}^{0} \to K^{0}\rho^{0}(\omega)\to K^{0}\pi^{+}\pi^{-}$ including the effect of $\rho-\omega$…

The best place to search for direct CP violation is the already observed charmless $b\to s$ modes. In SM with FSI, $a_{CP}$ in $K\pi$ modes could be as large as 20-30% but differ in sign between $K^-\pi^+/K^-\pi^0$ and $\bar K^0 \pi^-$. We…

We report a study of the charmless hadronic decay of the charged $B$ meson to the three-body final state $K^+ K^- \pi^+$. The results are based on a data sample that contains $772\times10^6$ $B \bar{B}$ pairs collected at the $\Upsilon(4S)$…
