Scalar-meson model for the decays ′, →π+π-γ
Physical Review D
The radiative decays ′, →π+π-γ are studied within the framework of a scalar-meson-dominance model in which the decays are mediated by ε(800) and ε′(1425) scalar resonances. By invoking an extended version of vector-meson dominance, we calculate the decay widths and dipion mass spectra for these processes. We find that although the decay widths are small (∼1 eV), they may be accessible to measurement in future experiments. © 1982 The American Physical Society.
