Huge right-handed current effects in B->K*(K pi)l+l- in supersymmetry
Transverse asymmetries in the decay B {yields} K*(K{pi}){ell}{sup +}{ell}{sup -} are an extremely sensitive probe of right-handed flavor-changing neutral currents. They show how to include the contribution from the chiral partner of the electromagnetic operator on the transverse asymmetries at NLO in QCD factorization. They then consider supersymmetric models with non-minimal flavor violation in the down-squark sector. They include all the relevant experimental constraints and present a numerical formula for B {yields} X{sub s}{gamma} that takes into account the most recent NNLO calculations. they show that the flavor-changing parameters of these models are poorly constrained by present data and allow for large effects on the transverse asymmetries that they consider.
