Résumé : We present upgraded theoretical predictions for inclusive and exclusive radiative decays of B mesons. Our results include those next-to-leading order corrections that have already been computed. Our best estimates in the Standard Model are BR(B → K* γ) = (4 3 ± 0.9-10+14) × 10-5, BR(B → Xsγ) = (1.9 ± 0.2 ± 0.5) × (10-4, Γ (B → K* γ)/Γ(B → K*sγ) = 0.23 ± 0.09 and BR(B → Xsg) = (1.57 ± 0.15-059+086 ± 0.23) × 10-3. We also consider limits found with two-Higgs-doublet models.
