Large and Fun CP Violation in B Meson Decays: Where to Search?
Abstract
Description
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 $Kπ$ modes could be as large as 20-30% but differ in sign between $K^-π^+/K^-π^0$ and $\bar K^0 π^-$. We illustrate possible New Physics effects that could lead to $a_{CP}$ of order 40-60% in $Kπ$ and $ϕK$ modes distinguishable from FSI. $b\to sγ$ modes can also exhibit interesting asymmetries.
