We review some recent progress in the theory of electroweak radiative corrections in semileptonic decay processes. The resurrection of the so-called Sirlin’s representation based on current algebra relations permits a clear separation between the perturbatively-calculable and incalculable pieces in the O(GFα) radiative corrections. The latter are expressed as compact hadronic matrix elements that allow systematic non-perturbative analysis such as dispersion relation and lattice QCD. This brings… Expand

Improved Ke3 radiative corrections sharpen the Kμ2–Kl3 discrepancy
Abstract The measurements of Vus in leptonic (Kμ2) and semileptonic (Kl3) kaon decays exhibit a 3σ disagreement, which could originate either from physics beyond the Standard Model or some largeExpand

Leading hadronic contribution to the muon magnetic moment from lattice QCD.
TLDR
Substantial precision is reached to discriminate between the measurement of the anomalous magnetic moment of the muon and the predictions of dispersive methods, which favours the experimentally measured value over those obtained using the dispersion relation. Expand
