| 英文摘要 | The scalar and vector meson exchange contributions to the doubly radiative decays eta(()'()) -> pi(0)gamma gamma( )and eta' -> eta gamma gamma are analyzed within the linear sigma model and vector meson dominance frameworks, respectively. Predictions for the diphoton invariant mass spectra and the associated integrated branching ratios are given and compared with current available experimental data. While a satisfactory description of the shape of the eta -> pi(0)gamma gamma and eta' -> pi(0)gamma gamma decay spectra is obtained, thus supporting the validity of the approach, the corresponding branching ratios cannot be reproduced simultaneously. A first theoretical prediction for the recently measured it eta' -> eta gamma gamma by the BESIII Collaboration is also presented. |
