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