Abstract

Using e⁺e^- collision data, corresponding to an integrated luminosity of 892 \rm pb^-1 collected at center-of-mass energies from 4.84 to 4.95 GeV with the BESIII detector, we search for the process e⁺e^-→ K⁺ K^- ψ(3770) by reconstructing two charged kaons and one D meson from ψ(3770). No significant signal of e⁺e^-→ K⁺ K^- ψ(3770) is found and the upper limits of the Born cross sections are reported at 90% confidence level.
