Measurement of the ${e}^{+}{e}^{-}\to p\overline{p}{\pi }^{0}$ cross section at $\sqrt{s}=2.1000-3.0800\text{}\text{}\mathrm{GeV}$

The process ${e}^{+}{e}^{-}\to p\overline{p}{\pi }^{0}$ is studied at 20 center-of-mass energies ranging from 2.1000 to 3.0800 GeV using $636.8\text{}\text{}{\mathrm{pb}}^{-1}$ of data collected with the BESIII detector operating at the BEPCII collider. The Born cross sections for ${e}^{+}{e}^{-}\to p\overline{p}{\pi }^{0}$ are measured with high precision. Since the lowest center-of-mass energy, 2.1000 GeV, is less than 90 MeV above the $p\overline{p}{\pi }^{0}$ energy threshold, we can probe the threshold behavior for this reaction. However, no anomalous threshold enhancement is found in the cross sections for ${e}^{+}{e}^{-}\to p\overline{p}{\pi }^{0}$.
