Abstract

The observed strong phase difference of 30^o between I=(3/2) and I=(1/2) final states for the decay B to D Pi is analyzed in terms of rescattering like D^∗Pi to D Pi, etc. It is concluded that for the decay B^oto D⁺ Pi^- the strong phase is only about 10^o. Implications for the determination of sin(2 Beta + gamma) are discussed.
