Description

The decay eta' ->e+e- has been searched for at the VEPP-2000 e+e- collider with the SND detector using the reaction e+e- -> eta'. The following upper limits have been set at the 90% CL: Gamma(eta' -> e+e-) < 0.0020 eV and B(eta' -> e+e-) < 10^-8. Sensitivity of VEPP-2000 for measurement of the e+e- -> eta cross section has been studied.
