✦ Synopsis

The renormalization group is used to resum leading logarithmic contributions of the form α n+1 s β n 0 log n ( /µ) to the gap equation appropriate for high-density QCD. The scale dependence of the strong coupling constant α s increases the gap by a factor of exp 33 16 π 2 4 -1 ∼ 20 in the small coupling limit.
