A Role of the Axial Vector Mesons on the Photon Production in Heavy Ion Collisions and Their Relevant Decays

Yun Chang Shin, Myung Ki Cheoun, K. S. Kim +1

A role of the axial vector mesons, such as $K_1$ and $a_1$, on the emitted photon spectrum in hot hadronic matter is studied through the channels $\pi \rho \to a_1\to \pi \gamma$ and $K ρ\to K_1…
