SUPERSYMMETRIC CONTRIBUTIONS TO B→K π IN THE VIEW OF RECENT EXPERIMENTAL RESULTS

Abstract

Supersymmetric contributions to the branching ratios and CP asymmetries of B→K π decays are analyzed in view of recent experimental measurements. We show that supersymmetry can still provide a natural solution to the apparent discrepancy between the CP asymmetry results and the Standard Model expectations. We emphasize that chargino contributions may enhance the electroweak penguin effects that can resolve to the puzzle of the CP asymmetries of B→Kπ. We also point out that a nonuniversal A-terms is an essential requirement for this solution.
