Pion Cloud Effects on -N Mass Splitting from Quark Models
收藏 引用
Communications in Theoretical Physics 2002年 第8期38卷 189-194页
作者: DONG Yu-Bing FENG Qing-Guo Institute of High Energy Physics the Chinese Academy of Sciences P.O. Box 918-4 Beijing 100039 China Institute of High Energy Physics the Chinese Academy of Sciences P.O. Box 918-4 Beijing 100039 China
Pion cloud effects on -N mass splitting are studied based on quark models. Pseudo-scalar pion-quarkcoupling is discussed in the relativistic and nonrelativistic frameworks. We separately calculate the pion cloud eff...
