Photons from axial-vector radiative decay in a hadron gas.

Strange and non-strange axial-vector meson radiative decays contribute to photon production in hadron gas. Oneand two-hadron radiative decay modes of b1(1235), a1(1260) andK1(1270) are studied. At 200 MeV temperature and for a narrow range in photon energies they contribute more to the net thermal photon production rate than πρ → πγ, ππ → ργ or ρ → ππγ. They provide significant contribution to the rate for photon energies as high as 1.5–2.0 GeV. For higher energies they are less important.
