We analyze a forward scattering model on a square lattice, which exhibits spontaneous Fermi surface symmetry breaking with a d-wave order parameter: the Fermi surface expands along the k x -axis and shrinks along the k y -axis or vice versa. While the transition is usually first order as a function
