Anomalous decay of pion and eta at finite density

We study the anomalous decays [pi]0, [eta]-->[gamma][gamma] in the framework of the three-flavor Nambu-Jona-Lasinio [NJL] model, in the vacuum and in quark matter in [beta]-equilibrium. It is found that the behavior of the relevant observables essentially reflects a manifestation of the partial r...
