Abstract: QCD superconductors in the color-flavor-locked (CFL) phase sustain light Goldstone modes(that will be referred to as generalized pions) that can be described as pairs of particle and/or hole excitations around a gapped Fermi surface. TI weak coupling and to leading logarithm accuracy, their form factor, mass and decay constant can be valuated exactly. These modes are found to satisfy an axial-Ward-identity, constraining the mass of the Goldstone modes in the CFL phase. (C) 2000 Elsevier Science B.V. All rights reserved.
