Time-dependent angular analyses of B decays

Abstract

When both B0 and B0bar can decay to the same final state composed of two vectors, the interference between them and those among three polarization states result in intricate phenomena. In this note we derive the time and angular distributions for general B to Va Vb processes in a form convenient for actual analyses. We then apply them to specific examples and clarify the CP violating parameters obtainable in the D* rho and J/ψK* final states. The time distributions for the D*pi final states are also discussed.
