Abstract: We present a systematic analysis at the leading log order of the influence of combination of bilinear and trilinear R parity violating couplings on the decay b→s+γ. Such contributions have never been explored in the context of b→s+γ decay. We show that influence of charged-slepton-Higgs mixing mediated loops can dominate the SM and MSSM contributions and hence can provide strong bounds on the combination of bilinear-trilinear R parity violating couplings. Such contributions also are enhanced by large tanβ. With substantially extended basis of operators (28 operators), we provide illustrative analytical formulas of the major contributions to complement our complete numerical results which demonstrate the importance of QCD running effects.
