Cross section measurement of $ {e}^{+}{e}^{-}\to {f}_{1}(1285){\pi }^{+}{\pi }^{-}$ at center-of-mass energies between 3.808 and 4.951 GeV

Using data samples collected by the BESIII detector located at the Beijing Electron Positron Collider, the cross sections of the process $ {e}^{+}{e}^{-}\to {f}_{1}(1285){\pi }^{+}{\pi }^{-}$ are measured at 45 center-of-mass energies from 3.808 to 4.951 GeV. An investigation on the energy-dependent cross section is performed, and no significant structure is observed.
