| 英文摘要 | By using the cross sections of e+e-→p p ¯ π0 measured at the center-of-mass energies from 3.65 to 4.60 GeV, we find that the line shape well agrees with pure continuum production parametrized by a power law function and the significance of both ψ (3770 ) and ψ (4230 )→p p ¯ π0 is less than 0.4 σ . We set more stringent constraints on the charmless decays of the charmonium state, ψ (3770 ), and the charmoniumlike state, ψ (4230 ), to p p ¯π0 than in previous measurements. The data are also used to estimate the cross sections of p p ¯ →π0ψ (3770 ) and p p ¯ →π0ψ (4230 ) that are essential for planning the data taking of the P ¯ ANDA experiment. |
