  "abstract": "<p>We report a study of the ${e}^{+}{e}^{-}\\to {D}^{+}{D}^{-}{\\pi }^{+}{\\pi }^{-}$ process using ${e}^{+}{e}^{-}$ collision data samples with an integrated luminosity of $2.5\\phantom{\\rule{0.2em}{0ex}}{\\text{fb}}^{-1}$ at center-of-mass energies from 4.36 to 4.60GeV, collected with the BESIII detector at the BEPCII storage ring. The ${D}_{1}{\\left(2420\\right)}^{+}$ is observed in the ${D}^{+}{\\pi }^{+}{\\pi }^{-}$ mass spectrum. The mass and width of the ${D}_{1}{\\left(2420\\right)}^{+}$ are measured to be $\\left(2427.2\u00b1{1.0}_{\\mathrm{stat}.}\u00b1{1.2}_{\\mathrm{syst}.}\\right)$MeV/${c}^{2}$ and $\\left(23.2\u00b1{2.3}_{\\mathrm{stat}.}\u00b1{2.3}_{\\mathrm{syst}.}\\right)$MeV, respectively. In addition, the Born cross sections of the ${e}^{+}{e}^{-}\\to {D}_{1}{\\left(2420\\right)}^{+}{D}^{-}+c.c.\\to {D}^{+}{D}^{-}{\\pi }^{+}{\\pi }^{-}$ and ${e}^{+}{e}^{-}\\to \\psi \\left(3770\\right){\\pi }^{+}{\\pi }^{-}\\to {D}^{+}{D}^{-}{\\pi }^{+}{\\pi }^{-}$ processes are measured as a function of the center-of-mass energy.</p>",
