高能激发与质子自旋结构 STIMULATION AT HIGH ENERGY SCALE AND SPIN STRUCTRUE OF PROTON 端怀宇 Duan Huaiyu 1 first-author 刘觉平 Liu Jueping 1 武汉大学物理学系 武汉大学物理学系 Department of Physics,Wuhan University Department of Physics,Wuhan University 在重子三夸克加五夸克模型的基础上,利用场论方法进一步估算了高能情况下质子内各五夸克组分所占比重,从而得到了此模型下质子内各味夸克对于自旋贡献的理论值 Field theory method is used to estimate the relative weights between different quark components in a simple three querk plus five quark model for an excited proton at high energy level.An abnomal spin structure of proton is thus obtained. 质子 自旋 夸克模型 proton spin quark model O572.22;O572.25 国家自然科学基金(61672102) 1998-03-01 2021-04-01 3
