Radiative Scalar-Meson Decays f(0)(980) -> rho(omega)gamma and a(0)(980) -> rho(omega)gamma within the Local Nambu-Jona-Lasinio Model

摘要

The widths with respect to the radiative decays f(0)(980) -> rho gamma and a(0)(980) -> omega gamma were calculated within the local Nambu-Jona-Lasinio model. The contributions of both quark and meson loops were taken into account. The latter and the former play a dominant role for the radiative decays of, respectively, the f(0)(980) and the a(0)(980) meson.
