Jun He, Bijan Saghai, Zhenping Li, Qiang Zhao, Johan Durand

摘要:

我们发展了一个组分夸克模型来描述该反应,使我们能够研究所有可用的微分截面和单极化不对称性的数据(光束和目标)通过包括PDG的{ \it all},一到四颗星,核子共振($S_{11}$、$P_{11}$、$P_{13}$、$D_{13}$、$D_{15}$、$F_{15}$、$F_{17}$、$G_{17}$、$G_{19}$、$H_{19}$、$I_{1,11}$、和$K_{1,13}$)。通过检查几种新共振($S_{11}$、$P_{11}$、$P_{13}$、$D_{13}$、$ D_{15}$和$H_{1,11}$)的可能贡献,还简要讨论了与缺失共振相关的问题。

英文摘要:

A constituent quark model is developed for the reaction, allowing us to investigate all available data for differential cross sections as well as single polarization asymmetries (beam and target) by including {\it all} of the PDG, one to four star, nucleon resonances ($S_{11}$, $P_{11}$, $P_{13}$, $D_{13}$, $D_{15}$, $F_{15}$, $F_{17}$, $G_{17}$, $G_{19}$, $H_{19}$, $I_{1,11}$, and $K_{1,13}$). Issues related to the missing resonances are also briefly discussed by examining possible contributions from several new resonances ($S_{11}$, $P_{11}$, $P_{13}$, $D_{13}$, $ D_{15}$, and $H_{1,11}$).
