英文摘要 | We study the charmonium p (p) over bar -> psi(3770)pi(0) reaction using the effective Lagrangian approach where the contributions fromwell- established N* states are considered, and all parameters are fixed in the process of e(+)e(-) -> p (p) over bar pi(0) at center of mass energy root s = 3.773GeV. The experimental data on the line shape of the mass distribution of the e(+)e(-) -> p (p) over bar pi(0) can be well reproduced. Based on the study of e(+)e(-) -> p (p) over bar pi(0), the total and differential cross sections of the p (p) over bar -> psi(3770)pi(0) reaction are predicted. At the same time we evaluated also the cross sections of the p (p) over bar -> psi(3770)pi(0) reaction. It is shown that the contribution of the nucleon pole to this reaction is largest close to the reaction threshold. However, the interference between nucleon pole and the other nucleon resonance can still change the angle distributions significantly. Those theoretical results may be tested by the future experiments at PANDA. |
