Renormalization Group Improved Gap Equation for Color Superconductors
arXiv:nucl-th/0004013 · doi:10.1016/S0375-9474(00)00595-9
Abstract
The renormalization group is used to resum leading logarithmic contributions of the form alpha_s^{n+1} beta_0^n 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)) ~ 20 in the small coupling limit.
