Abstract
A field theory involving two interacting scalar fields, previously studied by Rummukainen and Gottlieb, is revisited. Our study is not restricted to the limit of large quartic couplings, and a Symanzik-improved action is used so that continuum dispersion relations work well. The Metropolis method, combined with a local microcanonical updating algorithm, is employed in our Monte Carlo calculations. Isotropic lattices ranging from $16^3 \times 48$ to $53^3 \times 48$ are used, and scattering phase shifts are determined using a L\"uscher analysis with multiple partial waves.
