Abstract
In low energy supersymmetric (SUSY) theories the exchange of a gluino and squark with left-right mixing can produce a large gluonic dipole interaction. In this paper we study the effects of this interaction on B→Kπ using the QCD improved factorization method. The standard model predicts a smaller branching ratio for B0→K̄0π0 than the experimentally measured one. We find that, within the parameter space allowed from the B→γXs constraint, the SUSY dipole interaction can enhance this branching ratio to agree with the experimental measurement. Combining recent data for all four B̄0→K-π+,K̄ 0π0 and B-→K-π0,K̄0π - decay modes, we find that the allowed parameter space is reduced significantly compared with that using B →Xsγ data alone. It is found that even with these constraints, the predictions for CP violation in these modes can be dramatically different from those of standard model predictions.
