A Dalitz-plot analysis of Bd(t) -> rho pi -> pi+ pi- pi0 decays allows one to
obtain the CP-violating phase \alpha. 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.
