PHOTONS FROM AXIAL-VECTOR RADIATIVE DECAY IN A HADRON GAS

Strange and nonstrange axial-vector meson radiative decays contribute td photon production in hadron gas. One- and two-hadron radiative decay modes of b(1)(1235), a(1)(1260), and K-1(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 pi p -> pi gamma, pi pi -> p gamma, or p -> pi pi gamma. 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.
