Determining Strong and Weak Phases in Bd -> D⁽*⁾± D⁽*⁾∓ Decays

Original · EN

We show that both the weak phase βand the strong phase δd can be determined from the time-dependent measurement of Bd -> D*± D∓ decays, whose final states are non-CP eigenstates. It is also possible to extract βfrom Bd -> D*± D*∓ transitions without doing the angular analysis. Possible final-state rescattering effects in Bd -> D⁽*⁾± D⁽*⁾∓ channels are discussed by means of the isospin analysis. We emphasize that it is worthwhile to check whether the naive factorization approximation works or not for such B-meson decay modes into two heavy charmed mesons.
