Findings
Phase shifts for l=0 and l=2 are consistent with theoretical expectations.
Results show short-range repulsion and intermediate-range attraction.
Method successfully extracts discrete energy levels from correlation matrices.
Abstract
Scattering phase shifts of a meson-meson system in staggered 3-dimensional lattice QED are computed. The main task of the simulation is to obtain a discrete set of two-body energy levels. These are extracted from a 4-point time correlation matrix and then used to obtain scattering phase shifts. The results for the l=0 and l=2 partial waves are consistent with short- range repulsion and intermediate-range attraction of the residual meson- meson interaction.
