非平凡拓扑区域中的广义Hedgehog映射和Gribov拷贝

Generalized Hedgehog ansatz and Gribov copies in regions with non trivial topologies

Fabrizio Canfora, Patricio Salgado-Rebolledo

摘要:

本文分析了在具有非平凡拓扑但为平坦度规的区域(如闭管S1XD 2或RXT 2)中朗道规范和库仑规范中Gribov副本的产生。使用一个新的广义的刺猬anomaly超越球对称,分析的例子格里博夫副本的真空将被构造。利用这种方法,我们还将构造椭圆Gribov摆。真空的Gribov副本满足强边界条件的情况下的要求意味着几何约束的形状和大小的区域与非平凡的拓扑结构。

英文摘要:

In this paper the arising of Gribov copies both in Landau and Coulomb gauges in regions with non-trivial topologies but flat metric, (such as closed tubes S1XD2, or RXT2) will be analyzed. Using a novel generalization of the hedgehog ansatz beyond spherical symmetry, analytic examples of Gribov copies of the vacuum will be constructed. Using such ansatz, we will also construct the elliptic Gribov pendulum. The requirement of absence of Gribov copies of the vacuum satisfying the strong boundary conditions implies geometrical constraints on the shapes and sizes of the regions with non-trivial topologies.
