直接从QCD拉氏量研究禁闭的尝试

A Try to Investigate Color Confinment Directly from QCD Lagrangian

摘要: 对SU(N)情形，应用法捷耶夫和尼米的非阿贝尔规范势的拓扑分解，在路径积分中，将除拓扑自由度以外的其它自由度积掉，求出单圈和低能近似下的有效作用量. 结果支持由对偶迈斯纳效应造成色禁闭的图像. 也讨论了费米子场的效应. In the SU(N) case we use the FadeevNiemi topological decomposition of nonabelian gauge potentials to derive the low energy effective Lagrangian under one loop approximation by integrating all degrees of freedom except the topological ones in its path integral. The result supports a mechanism on color confinment which comes from the dual Misner Effect. The effect from fermion fields is also discussed.
