  QCD superconductors in the color-flavor-locked (CFL) phase support light
excitations (generalized pions) in the form of particle-particle or hole-hole
excitations. We analyze the generalized process
$\tilde\pi^0\to\tilde{\gamma}\tilde{\gamma}$ in the weak coupling limit and
show that it is related to the recently suggested Wess-Zumino-Witten (WZW)
term. In dense QCD, the radiative decay of the generalized pion is constrained
by geometry and vanishes at large density.
