The pion_0 to gamma gamma decay and the chiral anomaly in the quark-composites approach to QCD

Sergio Caracciolo, Fabrizio Palumbo

We evaluate the pion_0 into two gammas decay amplitude by an effective action derived from QCD in the quark composites approach, getting the standard value. We also verify that our…
