Renormalization group improved gap equation for color superconductors

The renormalization group is used to resum leading logarithmic contributions of the form alpha (n+1)(s)beta (n)(0)log(n)(Delta/mu) to the gap equation appropriate for high-density QCD. The scale dependence of the strong coupling constant alpha (s) increases the gap by a factor of exp(33/16(pi (2)/4 - 1)) similar to 20 in the small coupling limit. (C) 2001 Elsevier Science B.V.
