abstract = "Using 푒+⁢푒− collision data collected with the BESIII detector at the BEPCII collider at 32 center-of-mass energies from 3.50 to 4.95 GeV, corresponding to an integrated luminosity of 25 fb−1, we measure the Born cross section of the 푒+⁢푒− →Σ0⁢¯Σ0 reaction and the effective form factor for the first time. No significant charmonium(-like) state, i.e., 휓⁡(3770), 휓⁡(4040), 휓⁡(4160), 휓⁡(4230), 휓⁡(4360), 휓⁡(4415), or 휓⁡(4660), decaying into the Σ0⁢¯Σ0 final state is observed by fitting the 푒+⁢푒− →Σ0⁢¯Σ0 dressed cross section. The upper limits for the product of the branching fraction and the electronic partial width at the 90% confidence level are provided for each assumed charmonium(-like) state for the first time. In addition, the ratios of the Born cross section and the effective form factor between the 푒+⁢푒− →Σ0¯Σ and the 푒+⁢푒− →Σ+⁢¯Σ− reactions are provided, which can be used to validate the prediction of the vector meson dominance model.",
