Abstract

The paper deals with a next-to-leading order analysis of the radiative B → K^* γ decay. Working in a PQCD approach, we compute the correction to the essential form factor, coming from a single gluon exchange with the spectator. We investigate the supersymmetry effects on the branching ratio and direct CP asymmetry and constrain the squark mixing parameter (δ₂₃^d)_LR.
