Scattering phases for fermion-fermion scattering in the Gross-Neveu model
arXiv:hep-lat/9509059 · doi:10.1016/0920-5632(96)00185-5
Abstract
We extract scattering phases for fermion-fermion scattering from Monte Carlo simulations of the two-dimensional Gross-Neveu model. This is done by means of Lüscher's method, which exploits the volume dependence of the energies of two-particle states. The results are compared with the analytical predictions.
