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⁻→pp¯π⁰ 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⁻→Y(4260)→pp¯π⁰ at the 90% C.L. is determined to be 0.01 pb. The upper limit on the ratio of the branching fractions [Formula presented] at the 90% C.L. is determined to be 0.02%.
