$a_1(1260)$ contribution to photon and dilepton productions from hot hadronic matter : Revisited

Abstract

We consider the $a_1(1260)$ contribution to photon and dilepton productions from hot hadronic matter. The effective lagrangian with $\pi ,\rho$ and $a_1$ discussed by Ko and Rudaz is employed, which successfully reproduces the $\Gamma (a_1\to \pi \gamma )=670$ keV. Our results for the photon production rate are comparable to those obtained by Xiong {\it et al.}, while the dilepton production rates come out smaller than those obtained by Gale {\it et al.} by an order of magnitude.
