Abstract

Complete expressions of the sbg and sb\ensuremathγ vertices are derived in the framework of supersymmetry with minimal flavor violation. As examples, the branching ratios of charmless B decays [\stackrel\ensuremath→BK+X (no charm)] and exclusive processes B_s\ensuremath→\ensuremathγ\ensuremathγ are calculated with the minimal supergravity assumptions.
