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 mu --> infinity and m/mu fixed. In particular. we find for the velocity of the NG boson the relation nu(2) = rootmu(1)(2) - m(1)(2)rootmu(2)(2) - m(2)(2)/3mu(1)mu(2).
