First Lattice QCD Determination of Lepton-Flavor-Universality Ratios in Light-Meson Leptonic Decays

Peter Boyle, Norman H. Christ, Xu Feng +4

The ratio of electronic to muonic leptonic decay widths, $R_{e / μ}$ , for the light mesons $π$ and $K$ , provides a clean test of lepton flavor universality (LFU) and a sensitive prob…
