The traditional cutoff regularization has difficulties for chemical potentials μ of the order of the cutoff Λ, predicting in particular a vanishing gap at μ~Λ. The proposed cutoff-independent regularization predicts a finite gap at high densities and indicates a smooth matching with the weak coupling QCD prediction for the gap at asymptotically high densities. © 2006 The American Physical Society.engArtigo10.1103/PhysRevC.73.0182012-s2.0-32644465767
