Strong Phases in the Decays B to D Pi
Abstract
The observed strong phase difference of 30o 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 Boto D+ Pi- the strong phase is only about 10o. Implications for the determination of sin(2 Beta + gamma) are discussed.
