Coulomb corrections to pi-pi scattering
Norman Christ, Xu Feng, Joseph Karpie +1
The relationship between finite volume multi-hadron energy levels and matrix elements and two particle scattering phase shifts and decays is well known, but the inclusion of long r…

scattering, QED and finite-volume quantization
Norman Christ, Xu Feng, Joseph Karpie +1
Using the Coulomb gauge formulation of QED we present a lattice QCD procedure to calculate the scattering phase shift including the effects of the Coulomb potential which…
