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, , for the light mesons and , provides a clean test of lepton flavor universality (LFU) and a sensitive pr…

Improvement in Autocorrelation Times Measured by the Master-Field Technique using Field Transformation HMC in 2+1 Domain Wall Fermion Simulations
Shuhei Yamamoto, Peter Boyle, Taku Izubuchi +3
The Field-Transformation Hybrid Monte-Carlo (FTHMC) algorithm potentially mitigates the issue of critical slowing down by combining the HMC with a field transformation, originally…
