最大阿贝尔规范中的Gribov视界和非微扰BRST对称性

Gribov horizon and non-perturbative BRST symmetry in the maximal Abelian gauge

M. A. L. Capri, D. Fiorentini, S. P. Sorella

摘要:

将[ arXiv:1506.06995 [hep-th]]中构造的朗道规范中Gribov-Zwanziger作用量的非微扰幂零精确BRST对称性推广到极大阿贝尔规范量子化的欧几里得Yang-Mills理论的情形.由此得到的对角胶子传播子在D= 4,3,2维中求值。在D= 4.3时,在红外区域发现去耦型行为,而在D=2时出现标度型行为。

英文摘要:

The non-perturbative nilpotent exact BRST symmetry of the Gribov-Zwanziger action in the Landau gauge constructed in [ arXiv:1506.06995 [hep-th]] is generalized to the case of Euclidean Yang-Mills theories quantized in the maximal Abelian gauge. The resulting diagonal gluon propagator is evaluating in dimensions D=4,3,2. In D=4,3 a decoupling type behavior is found in the infrared region, while in D=2 a scaling type behavior emerges.
