Description

The radiative decays UPSILON',UPSILON→π+π-γ are studied within the framework of a scalar-meson-dominance model in which the decays are mediated by the epsilon(800) and epsilon'(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 (approx.1 eV), they may be accessible to measurement in future experiments
