摘要
本文利用格点规范理论的方法讨论手征对称性的非阿贝尔陪集纯规范场对体系禁闭性质的影响。具体计算了陪集G/H=SU(2)_L×SU(2)_R/JU(2)模型的流-流传播子,发现陪集空间纯规范场只提供一个线度律因子,不影响物理系统的禁闭性质。
The influence of coset pure gauge fields of a non-abelian chiral group on confinement properties of a quark system is discussed in lattice gauge theories. By calculating the current-current propagator of the model G/H=SU(2)_L×SU(2)_R/SU(2), it is found that the pure gauge fields on coset space contribute only a perimeter law factor which has no influence on confinement properties of the system.
