Abstract :
The high density effective theory formalism (HDET) is employed to describe high density QCD with two massive flavors (2SC). The gap equation is derived and explicitly solved for the gap parameter. The parameters associated to the pseudo Nambu–Goldstone boson of U(1)A are evaluated in the limit μ→∞ and m/μ fixed. In particular, we find for the velocity of the NG boson the relation v2=μ12−m12 μ22−m22/3μ1μ2.
