Abstract
We present a systematic analysis of all the contributions at the leading log to the decay rate of b → s + γ in the framework of supersymmetry without R-parity. We focus on the influence of trilinear λ′ ijk couplings and report on the possibility of a few orders of magnitude improvement for the bounds on a few combinations of λ′. Our studies show that the Wilson coefficients of the current-current operators due to RPV dominate over the penguins. However, the inter play of various contributions is complicated, due to the QCD corrections which we elaborate here.
