  "description": "<p>Based on ${e}^{+}{e}^{-}$ annihilation data samples collected with the BESIII detector at the BEPCII collider at 13 center-of-mass energies from 4.008 to 4.600 GeV, measurements of the Born cross section of ${e}^{+}{e}^{-}\\to p\\overline{p}{\\pi }^{0}$ are performed. No significant resonant structure is observed in the measured energy dependence of the cross section. The upper limit on the Born cross section of ${e}^{+}{e}^{-}\\to Y\\left(4260\\right)\\to p\\overline{p}{\\pi }^{0}$ at the 90% C.L. is determined to be 0.01 pb. The upper limit on the ratio of the branching fractions $\\frac{B\\left(Y\\left(4260\\right)\\to p\\overline{p}{\\pi }^{0}\\right)}{B\\left(Y\\left(4260\\right)\\to {\\pi }^{+}{\\pi }^{-}J/\\psi \\right)}$ at the 90% C.L. is determined to be 0.02%.</p>",
