Abstract
A potential between mesons is extracted from 4-point functions within lattice gauge theory taking 2+1 dimensional QED as an example. This th eory possesses confinement and dynamical fermions. The resulting meson -meson potential has a short-ranged hard repulsive core and the expect ed dipole-dipole forces lead to attraction at intermediate distances. Sea quarks lead to a softer form of the total potential.
