De Martino, A. and Moriconi, M. (1999). Boundary S-matrix for the Gross-Neveu Model. Physics Letter B, 451(3-4), pp. 354-356. doi: 10.1016/S0370-2693(99)00240-3

Abstract

We study the scattering theory for the Gross-Neveu model on the half-line. We find the reflection matrices for the elementary fermions, and by fusion we compute the ones for the two-particle bound-states, showing that they satisfy non-trivial bootstrap consistency conditions. We also compute more general reflection matrices for the Gross-Neveu model and the nonlinear sigma model, and argue that they correspond to the integrable boundary conditions we identified in our previous paper hep-th/9809178.
