AB  - A bstract : Based on 8 . 5 fb − 1 of e ⁺ e − collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we investigate the process e^+e^−→ π^+π^−D_s^+D_s^− e + e − → π + π − D s + D s − . With no significant signal observed, upper limits on the Born cross sections of e^+e^−→ π^+π^−D_s^+D_s^− e + e − → π + π − D s + D s − at each energy value at the 90% confidence level are determined. Additionally, a search for intermediate charmonium-like resonances is performed in the M(D_s^+D_s^−) M D s + D s − invariant mass spectrum, but no significant resonant structures are observed with the current statistics.
