Search for $e^{+}e^{-}\to\eta'\psi(2S)$ at center-of-mass energies from 4.66 to 4.95 GeV

TL;DR

This study searches for the process $e^+e^- ightarrow ext{eta'} ext{psi}(2S)$ at energies 4.66-4.95 GeV using BESIII data, finding no significant signal and setting upper limits on the cross section.

Contribution

First search for $e^+e^- ightarrow ext{eta'} ext{psi}(2S)$ at these energies, providing upper limits on the cross section.

Findings

No significant signal observed.

Upper limits set on the cross sections.

Data collected with 4.67 fb^{-1} at BESIII.

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 $e^+e^- \rightarrow \eta' \psi(2S)$ 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 $\sigma^B(e^+e^-\rightarrow\eta'\psi(2S))$ at the 90\% confidence level are determined.
