CP Violation in B -> rho pi: New Physics Signals
Abstract
A Dalitz-plot analysis of Bd(t) -> rho pi -> pi+ pi- pi0 decays allows one to obtain the CP-violating phase α. In addition, one can extract the various tree (T) and penguin (P) amplitudes contributing to these decays. By comparing the measured value of |P/T| with the theoretical prediction, one can detect the presence of physics beyond the standard model.
