N2 - Using e+e− collision data at 13 center-of-mass energies ranging from 4.600 to 4.951 GeV collected with the BESIII detector, we conduct the first search for the e+e− → process and investigate the resonance structures in the cross section line shape. No significant signal is observed, and the upper limits of the Born cross sections at each center-of-mass energy are presented. The ratio is determined to be 0.15 ± 0.22. This result indicates that if vector states exist in this energy region, their decay into hc is significantly suppressed compared to decays into J/ψ.
