    "abstract": "We study superfluidity in a model of massless fermions coupled to a massive\nscalar field through a Yukawa interaction. Gap equations for a condensate with\ntotal spin J=0 are solved in the mean-field approximation. For the Yukawa\ninteraction, the gaps for right- and left-handed fermions are equal in\nmagnitude and opposite in sign, so that condensation occurs in the J^P = 0^+\nchannel. At finite scalar mass, there are two different gaps for fermions of a\ngiven chirality, corresponding to condensation of particle pairs or of\nantiparticle pairs. These gaps become degenerate in the limit of infinite\nscalar mass.",
