RI-(S)MOM to conversion for at two-loop order
Martin Gorbahn, Sebastian Jäger, Sandra Kvedaraitė
The Kaon bag parameter plays a critical role in constraining the parameters of the CKM matrix and in probing physics beyond the Standard Model. In this work, we imp…

SMOM - Matching for at Two-loop Order
Sebastian Jäger, Sandra Kvedaraitė
The Kaon bag parameter, , 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…
