Abstract

We summarize how a renormalization-group (RG)-consistent treatment removes well-known artifacts in NJL-model descriptions of colorsuperconducting quark matter. We introduce two RG-consistent schemes, "minimal" and "massless", and present analytic solutions for the diquark gap at T = 0 and for the phase boundary T c ( μ ) in symmetric massless matter, representing the high-density limit of the model. We compare the pairing gaps, phase diagram, and speed of sound with results obtained using conventional regularization.
