Scattering Cross Sections

We study glueball and meson scattering in compact QED2+1 gauge theory in a Hamiltonian formulation on a momentum lattice. We compute S-matrix elements and scattering cross sections and compare our results with strong coupling perturbation theory

Area Law

Recently, a fractal Wilson loop <FP> has been suggested to yield for non-compact SU(2) gauge theory an area law in the strong-coupling regime, while the standard Wilson loop <WP> yields a perimeter law. Here we consider non-compact U(1) gauge theory, compute the fractal Wilson loop analytically, and obtain a perimeter law for all coupling. We find that <FP> and <WP> coincide.
