Possibility of Large FSI Phases in Light of $B\to Kπ$ & $ππ$ Data
Abstract
Description
After briefly reviewing how data indicated that factorization seems to work in observed two body charmless modes, {\it if one takes $γ\gtap 90^\circ$}, we point out that the $K^0π^0$ mode seems too large. This and other hints suggest that perhaps not only $γ$ is large, but rescattering phase $δ$ could be sizable as well.
