Abstract: |
The branching ratio of the electromagnetic rare decays η→π0γγ and η'→(π0,η)γγ are analysed in terms of scalar and vector meson exchange contributions using the frameworks of the Linear Sigma Model and Vector Meson Dominance, respectively. The measured η→π0γγ process serves as a test of our approach while the non yet measured η'→(π0,η)γγ reactions are predicted for the first time. Our prediction for the η→π0γγ decay agrees with recent experimental reported values, thus supporting the validity of our framework. Therefore, our predictions for the η'→π0γγ and η'→ηγγ decays should be taken as a first indication of the possible values of the associated branching ratios. We hope these predictions to be interesting and useful for experiments such as KLOE-2, Crystal Ball, WASA, and BES-III where these processes are expected to be measured in the next future. |
