Strong Phases in the Decays B to pi pi

Abstract

Two sources of strong phases in the decays $B$ to $\pi \pi$ are identified: (1) "quasi-elastic scattering" corresponding to intermediate states like $\pi \pi$ and $\rho \rho$, (2) ``$c\bar{c}$'' corresponding to intermediate states like $D\bar{D}$ and $D^{\ast }{\bar{D}}^{\ast }$. Possibilities of using data to identify these two sources are discussed and illustrated. Present data suggests both sources may be significant.
