Abstract

We present an exact

α_{s}

calculation of the Wilson coefficients associated with the dipole moment operators. We also give an estimate of the branching ratio for

b \to s γ

. We find that higher dimensional effects are under control within 9% for

B (b \to s γ) = (4.3 \pm 0.37) \times 10^{- 4}

.
