ABSTRACT
Six $C$-even states, denoted as $X$, with quantum numbers $J^{PC}=0^{-+}$, $1^{\pm+}$, or $2^{\pm+}$, are searched for via the $e^+e^-\to\gamma D_{s}^{\pm}D_{s}^{*\mp}$ process using $(1667.39\pm8.84)~\mathrm{pb}^{-1}$ of $e^+e^-$ collision data collected BESIII detector operating at BEPCII storage ring center-of-mass energy $\sqrt{s}=(4681.92\pm0.30)~\mathrm{MeV}$. No statistically significant signal is observed in mass range from $4.08$ to $4.32~\mathrm{GeV}/c^{2}$. The upper limits $\sigma[e^+e^-\to\gamma X]\cdot \mathcal{B}[X \to D_{s}^{\pm}D_{s}^{*\mp}]$ a $90\%$ confidence level determined.
