One-loop Renormalization Group Equations in Generic Effective Field Theories. Part I: Bosonic Operators
MikoÅaj Misiak, Ignacy NaÅÄcz
We consider a generic class of effective quantum field theories with arbitrary gauge groups and scalar matter fields. In such theories, we derive the one-loop Renormalization Group…

Complete Corrections to the Leptonic Invariant Mass Spectrum in Decay
Mateusz Czaja, MikoÅaj Misiak, Abdur Rehman
In the determination of the Cabibbo-Kobayashi-Maskawa matrix element from inclusive semileptonic -meson decays, moments of the leptonic invariant mass spectrum consti…

Current Status of the Standard Model Prediction for the B_s -> mu^+ mu^- Branching Ratio
Mateusz Czaja, Mikolaj Misiak
The rare decay B_s -> mu^+ mu^- provides an important constraint on possible deviations from the Standard Model in b-s-l-l interactions. The present weighted average of its branchi…
