Renormalisation group evolution of the shape function g 17 in B ¯ → X s γ $$ \overline{B}\to {X}_s\gamma $$ and B ¯ → X s ℓ + ℓ − $$ \overline{B}\to {X}_s{\ell}^{+}{\ell}^{-} $$ at subleading power
Abstract We derive and solve the renormalisation-group (RG) equation of the shape function g 17(ω, ω 1; μ), which appears at subleading power in the factorisation of the inclusive decays B ¯ → X s γ $$ \overline{B}\to {X}_s\gamma $$ and B ¯ → X s ℓ + ℓ − $$ \overline{B}\to {X}_s{\ell}^{+}{\ell}^{-}...
