Effective meson-meson interaction in 2+1 dimensional lattice QED

Abstract

A definition of an effective meson-meson interaction adapted to the framework of a lattice simulation is presented. Results, based on a truncated momentum-space 4-point time correlation matrix, and preliminary data from a complementary coordinate-space simulation, are shown.
