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