Reanalysis of the e+e-→ηγ reaction cross section
In the experiment with the SND detector at the VEPP-2M e+e- collider measuring the e+e-→ηγ cross section in the energy range 0.6<s<1.38GeV the reanalysis of data is performed. The goal is to improve the accuracy of the previous results by analyzing ambiguities in the approximation of energy dependence of the e+e-→ηγ cross section, which were not taken into account in our previous study. We report new results on the approximation of the e+e-→ηγ cross section based on the vector dominance model under new model parameter assumptions. © 2007 The American Physical Society.
