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.

8 pages, 1 figure (included), plain LaTeX. Analysis modified: QCD factorization used instead of naive factorization; larger |P/T| range taken; figure changed; other minor changes; references updated. To be published in PRD: Brief Reports
