Abstract

Using e⁺e^- collision data at 13 center-of-mass energies ranging from 4.600 to 4.950 GeV collected with the BESIII detector, we search for the unmeasured e⁺e^-→ K_S⁰ K_S⁰ h_c process . No significant signal is observed, and the upper limits of the Born cross sections at each center-of-mass energy are presented.
