| contents | In all previous calculations of the non-local sub-leading contribution to the inclusive penguin decay $\bar B \to X_s γ$ due to the interference of the electroweak operators ${O}_1^c$ - ${O}_{7γ}$ the local Voloshin term was subtracted. In view of the ongoing analysis at order $α_s$, we present a calculation of the complete non-local contribution which takes into account the high correlation between the uncertainties of the local Voloshin and the non-local term of the previous analyses. The new calculation has a high impact on the range of the non-local contribution. |
