摘要
在重子波函数中考虑了s夸克与u ,d夸克质量的差别 ,构造了把坐标空间与味空间联合成SU(3) rf的SU(3) rf×SU(2 ) s×SU(3) c群分类夸克间全反对称的重子波函数 .与不考虑s夸克与u ,d夸克质量差的SU(n) r×SU(3) f×SU(2 ) s×SU(3) c群分类的波函数作了比较 。
According to the SU (3) rf × SU (2) s × SU (3) c group classification theory,? the total antisymmetric baryon wave functions are constracted,? in which the mass difference between s quark and light (u,?d) quark are considered. A comparison with the case of no mass difference between s and u,?d quark is made. It is shown that the mass difference effect is not negligible in the interaction energy matrix elements.
