Abstract

Using e(+)e(-) collision data, corresponding to an integrated luminosity of 892 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- psi(3770) by reconstructing two charged kaons and one D meson from psi(3770). No significant signal of e(+)e(-) -> K+K- psi(3770) is found and the upper limits of the Born cross sections are reported at 90% confidence level.
