Improved K e3 radiative corrections sharpen the K μ2–K l3 discrepancy

Abstract The measurements of V us in leptonic (K μ2) and semileptonic (K l3) kaon decays exhibit a 3σ disagreement, which could originate either from physics beyond the Standard Model or some large unidentified Standard Model systematic effects. Clarifying this issue requires a careful examination o...
