R-Parity violation in B --> pi+ pi- decay

Abstract

We consider the impact of R-parity violating suprsymmetry in the nonleptonic decay B --> pi+ pi-. This is one of the rare instances where new physics contributes to both B-Bbar mixing and B --> pi+ pi- decay. We do a numerical analysis to capture the interplay between these two effects and place constraints on the relevant parameter space.
