Search for $e^+e^-\to K^+ K^- ψ(3770)$ at center-of-mass energies from 4.84 to 4.95 GeV

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 $e^+e^-\to K^+ K^- \psi(3770)$ by reconstructing two charged kaons and one $D$ meson from $\psi(3770)$. No significant signal of $e^+e^-\to K^+ K^- \psi(3770)$ is found and the upper limits of the Born cross sections are reported at 90\% confidence level.
