Abstract

Based on 106×106ψ(3686) events collected with the BESIII detector at the BEPCII facility, a partial wave analysis of ψ(3686) →pp̄π0 is performed. The branching fraction of this channel has been determined to be B(ψ(3686)→pp̄π0)=(1.65±0. 03±0.15)×10^-4. In this decay, 7 N^* intermediate resonances are observed. Among these, two new resonances, N(2300) and N(2570) are significant, one 1/2⁺ resonance with a mass of 2300-30-0+40+109 MeV/c2 and width of 340-30-58+30+110 MeV/c2, and one 5/2 ^- resonance with a mass of 2570-10-10+19+34 MeV/c2 and width of 250-24-21+14+69 MeV/c2. For the remaining 5 N^* intermediate resonances [N(1440), N(1520), N(1535), N(1650) and N(1720)], the analysis yields mass and width values that are consistent with those from established resonances.
