Abstract

A detailed analysis of the effects of supersymmetric models without R parity on various CP asymmetries in neutral B decays is given. We concentrate on models with Abelian horizontal symmetries that allow us to estimate the order of magnitude of the new effects. We focus on channels where the standard model gives clean predictions: B_d→ψK_S and B_d→φK_S. In the presence of new physics the two asymmetries can have a value different from sin 2β. Moreover, they can be different from each other.
