Measurement of $e^+ e^- \rightarrow \phi \eta^{\prime}$ cross sections at center-of-mass energies between 3.508 and 4.600 GeV

TL;DR

This paper measures the cross sections of the process $e^+ e^- ightarrow \,\phi \,\eta^{\prime}$ across energies from 3.508 to 4.600 GeV and searches for the decay of $Y(4230)$, finding no significant signal.

Contribution

First measurement of $e^+ e^- ightarrow \,\phi \,\eta^{\prime}$ cross sections in this energy range with a search for $Y(4230)$ decay.

Findings

No significant $Y(4230) \to \phi \eta^{\prime}$ signal observed.

Upper limits set on the decay process.

Cross sections measured across the specified energy range.

Abstract

We present a measurement of the dressed cross sections for $e^+ e^- \rightarrow \phi \eta^{\prime}$ at different center-of-mass energies between 3.508 and 4.600 GeV based on 15.1 fb$^{-1}$ of $e^+ e^-$ annihilation data collected with the BESIII detector operating at the BEPCII collider. In addition, a search for the decay $Y(4230) \to \phi \eta^{\prime}$ is performed. No clear signal is observed and the corresponding upper limit is provided.
