Abstract
We study glueball and meson scattering in compact QED2+1 gauge theory in a Hamiltonian formulation on a momentum lattice. We compute ground state energy and mass, and introduce a compact lattice momentum operat or for the computation of dispersion relations. Using a non-perturbati ve time-dependent method we compute scattering cross sections for glue balls and mesons. We compare our results with strong coupling perturba tion theory.
