Matching Conditions for $b \rightarrow s\gamma$ and $b \rightarrow s$ gluon in Extensions of the Standard Model
We evaluate matching conditions for the Wilson coefficients of operators mediating the $b \to s \gamma$ and $b \to s gluon$ transitions in a large class of extensions of the Standard Model. The calculation is performed at the leading order in flavor-changing couplings and includes two-loop QCD corre...
