    "abstract": "We employ a bispinor gap equation to study superfluidity at nonzero chemical\npotential: mu .neq. 0, in two- and three-colour QCD. The two-colour theory,\nQC2D, is an excellent exemplar: the order of truncation of the quark-quark\nscattering kernel: K, has no qualitative impact, which allows a straightforward\nelucidation of the effects of mu when the coupling is strong. In rainbow-ladder\ntruncation, diquark bound states appear in the spectrum of the three-colour\ntheory, a defect that is eliminated by an improvement of K. The corrected gap\nequation describes a superfluid phase that is semi-quantitatively similar to\nthat obtained using the rainbow truncation. A model study suggests that the\nwidth of the superfluid gap and the transition point in QC2D provide reliable\nquantitative estimates of those quantities in QCD.",
