Abstract

We determine the resonant parameters of the vector states and by performing a combined fit to the cross sections from the threshold to measured by the BaBar, Belle, BESIII, and CMD-3 experiments. The mass and width are obtained for , and the mass and width are obtained for . The statistical significance of is . Depending on the interference between , , and a non-resonant amplitude in the nominal fit, we obtain four solutions and , , or , and , , or . We also search for the production of , and the significance is only . We then determine the upper limit of at the 90% confidence level.
