V_ud and V_us: CKM 2010 working group I summary
arXiv:1112.0238
Abstract
The present status of universality tests of the weak couplings for quarks and leptons is reviewed, with updated information for the muon lifetime and for first-row inputs in the CKM matrix. We discuss the impact of this high-precision SM test in constraining new physics models. We also discuss a precise lepton flavor-violation test from leptonic K decays and recent progress in K-Kbar mixing.
