We analyze the generalized process $\tildeπ^0\to\tildeγ\tildeγ$ 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.7 pages, 1 figureHigh Energy Physics - PhenomenologyNuclear Theorytext
