Reduction of Charm Quark Mass Scheme Dependence in $\bar{B} \to X_{s}\gamma$ at the NNLL Level
The uncertainty of the theoretical prediction of the $\bar B \to X_s \gamma$ branching ratio at NLL level is dominated by the charm mass renormalization scheme ambiguity. In this paper we calculate those NNLL terms which are related to the renormalization of $m_c$, in order to get an estimate of the...
