# Cross section measurements of $e^{+}e^{-}\rightarrow p \bar{p} \pi^{0}$ at center-of-mass energies between 4.008 and 4.600 GeV

## TL;DR

This paper reports measurements of the cross section for the process $e^+e^- o p ar{p} \pi^0$ across energies from 4.008 to 4.600 GeV, finding no significant resonant structures and setting an upper limit on a specific decay channel.

## Contribution

First measurement of the energy-dependent cross section for $e^+e^- o p ar{p} \\pi^0$ in this energy range with no observed resonance.

## Key findings

- No significant resonant structure observed.
- Upper limit on $Y(4260) o p ar{p} \\pi^0$ decay is 0.01 pb.
- Cross section measurements across energies.

## Abstract

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 $e^{+}e^{-}\rightarrow p \bar{p} \pi^{0}$ are performed. No significant resonant structure is observed in the measured energy-dependent cross section. The upper limit on the Born cross section of $e^{+}e^{-}\rightarrow Y(4260) \rightarrow p \bar{p} \pi^{0}$ at the 90\% C.L. is determined to be 0.01 pb.
