dc.description.abstract	We show that theU(1) axial anomaly does not change if we take into account the temperature in the usual triangle diagram with two vector and one pseudovector couplings. We also calculate the modifications induced by the temperature on the decay width for the ?O decaying into two photons. It turns out that the decay width increases with the temperature in such a way that the dominant contribution comes from the thermal phase space.
