Abstract In a recent work, we calculated all three-loop diagrams contributing to the decay amplitude for b → sγ where none of the gluons touch the b-leg. In the present paper, we complete the calculation by working out all remaining three-loop dia

We present new contributions to the decay matrix element ${\mathrm{\ensuremath{\Gamma}}}_{12}^{q}$ of the ${B}_{q}\ensuremath{-}{\overline{B}}_{q}$ mixing complex, where $q=d$ or $s$. Our new results constitute the order ${\ensuremath{\alpha}}_{s}^{2
