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 prob…
Lattice Calculation of Light Meson Radiative Leptonic Decays
Peter Boyle, Norman H. Christ, Xu Feng +4
In this work, we perform a lattice QCD calculation of the branching ratios and the form factors of radiative leptonic decays () using doma…
Finite-volume formalism for physical processes with an electroweak loop integral
Xin-Yu Tuo, Xu Feng
This study investigates finite-volume effects in physical processes that involve the combination of long-range hadronic matrix elements with electroweak loop integrals. We adopt th…
Lattice calculation of electromagnetic corrections to decay
Norman H. Christ, Xu Feng, Luchang Jin +2
We describe a first-principles method to apply lattice QCD to compute the order corrections to decay. This method formulates the calculation in…
from lattice QCD
En-Hung Chao, Norman H. Christ, Xu Feng +1
We propose a lattice-QCD-suitable framework for computing the two-photon long-distance contribution to the complex decay amplitude, where QED is treate…
