The $$Q_{1,2}$$ Q 1 , 2 – $$Q_7$$ Q 7 interference contributions to $$b \rightarrow s \gamma $$ b → s γ at $${\mathcal O}(\alpha _{\mathrm s}^2)$$ O ( α s 2 ) for the physical value of $$m_c$$ m c
Abstract The $$\bar{B}\rightarrow X_s\gamma $$ B ¯ → X s γ branching ratio is currently measured with around $$5\%$$ 5 % accuracy. Further improvement is expected from Belle II. To match such a precision on the theoretical side, evaluation of $${\mathcal O}(\alpha _{\mathrm s}^2)$$ O ( α s 2 ) corre...
