Query: Beyond integrability: Baryon-baryon backward scattering in the massive
  Gross-Neveu model   Due to integrability, baryon-baryon scattering in the massless Gross-Neveu
model at large N features only forward elastic scattering. A bare mass term
breaks integrability and is therefore expected to induce backward elastic
scattering as well as inelastic reactions. We confirm these expectations by a
study of baryon-baryon scattering in the massive Gross-Neveu model near the
non-relativistic limit. This restriction enables us to solve the time-dependent
Hartree-Fock equations with controlled approximations, using a combination of
analytical methods from an effective field theory and the numerical solution of
partial differential equations.
