Prospects for DirectCPViolation in Exclusive and Inclusive CharmlessBDecays

Within the standard model, $\mathrm{CP}$ rate asymmetries for $B\to K^{-}{\pi }^{+,0\mathrm{}}$ could reach $10\%$. With strong final state phases, they could go up to $20\%$– $30\%$, even for the ${\overline{K}}^0{\pi }^{-}$ mode which would have the opposite sign. We can account for $K^{-}{\pi }^{+}$, ${\overline{K}}^0{\pi }^{-}$, and $\phi K$ rate data with new physics enhanced color dipole coupling and destructive interference. Asymmetries could reach $40\%$– $60\%$ for $K\pi$ and $\phi K$ modes and are all of the same sign. We are unable to account for the $K^{-}{\pi }^0$ rate. Our inclusive study supports our exclusive results.
