Abstract

In the light of new experimental results on B → Kπ decays, we study the decay processes B → K π in the framework of both R-parity conserving (SUGRA) and R-parity violating supersymmetric models. We find that any possible deviations from the Standard Model indicated by the current data for the branching ratios and the direct CP asymmetries of B → Kπ can be explained in both R-parity conserving SUGRA and R-parity violating SUSY models. However, there is a difference between the predictions of both models to the time-dependent CP asymmetry observable S_K_S π⁰ whose current experimental results include large uncertainties. We demonstrate that this difference can be useful for testing both models with more accurate data for S_K_S π⁰ and A_CP^+- in the near future.
