Beyond Leading Logarithms in $g_{V}$ : The Semileptonic Weak Hamiltonian at $O (α α_{s}^{2})$

Francesco Moretti, Martin Gorbahn, Sebastian Jaeger

We present the first next-to-leading-logarithmic QCD analysis of the electromagnetic corrections to the semileptonic weak Hamiltonian, including the mixed $O (α α_{s}^{2})$ c…

SMOM - $M S$ Matching for $B_{K}$ at Two-loop Order

Sebastian Jäger, Sandra Kvedaraitė

The Kaon bag parameter, $B_{K}$ , is a key non-perturbative ingredient in the search for new physics through CP-violation. It parameterizes the QCD hadronic matrix element of the effe…
