Search for $e^{+}{e}^{-}\to \hat{I}{\cdot }^{\prime }\ddot{I}ˆ(2S)$ at center-of-mass energies from 4.66 to 4.95 GeV

Abstract

Using data samples with an integrated luminosity of $4.67{\mathrm{fb}}^{-1}$ collected by the BESIII detector operating at the BEPCII collider, we search for the process $e^{+}{e}^{-}\to \hat{I}{\cdot }^{\prime }\ddot{I}ˆ(2S)$ at center-of-mass energies from $4.66$ to $4.95\mathrm{GeV}$. No significant signal is observed, and upper limits for the Born cross sections $\ddot{I}{ƒ}^B(e^{+}{e}^{-}\to \hat{I}{\cdot }^{\prime }\ddot{I}ˆ(2S))$ at the 90\% confidence level are determined.
