Abstract

Inspired by the existing calculation of B → πK decays in supersymmetry (SUSY), we evaluate the dominant SUSY contributions to B 0s →K+K-. We show that the observables of this process can be significantly modified in the presence of SUSY. In particular, the branching ratio can be increased considerably compared to the prediction of the standard model (SM). The effect is even more dramatic for the CP-violating asymmetries Adir and Amix. These asymmetries, expected to be small in the SM (Adir is predicted to take only positive values), change drastically with SUSY contributions. The measurement of these observables can therefore be used to detect the presence of physics beyond the SM, and put constraints on its parameters. © SISSA 2006.
