Photonic penguins at two loops and m_t-dependence of BR[ B -> X_s l^+ l^-]

Christoph Bobeth, Mikolaj Misiak, Joerg Urban

We calculate two-loop matching conditions for all the operators that are relevant to B -> X_s l^+ l^- decay in the Standard Model. In effect, we are able to remove the +_16% uncert…

Matching Conditions for $b \to s γ$ and $b \to s g l u o n$ in Extensions of the Standard Model

Christoph Bobeth, Mikolaj Misiak, Joerg Urban

We evaluate matching conditions for the Wilson coefficients of operators mediating the $b \to s γ$ and $b \to s g l u o n$ transitions in a large class of extensions of the Standard Mo…

QCD corrections to FCNC decays mediated by Z-penguins and W-boxes

Mikolaj Misiak, Joerg Urban

QCD corrections are evaluated to FCNC processes like $B \to X_{s} ν ν ˉ$ , $K \to π ν ν ˉ$ , $B \to l^{+} l^{-}$ or $K_{L} \to μ^{+} μ^{-}$ , i.e. to processes mediated by effective operators co…
