Scientific paper

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 illustrate possible New Physics effects that could lead to $a_{CP}$ of order 40-60% in $K\pi$ and $\phi K$ modes distinguishable from FSI. $b\to s\gamma$ modes can also exhibit interesting asymmetries.
