Standard functional manipulations have been proven to imply a remarkable property satisfied by the fermionic Green’s functions of QCD and dubbed effective locality. Resulting from a full gauge invariant summation of the gauge field degrees of freedom, effective locality is a non-perturbative property of QCD. This unexpected result has lead to suspect that the famous Gribov copy problem had been somewhat overlooked. It is argued that it is not so. The analysis is conducted in the strong coupling limit, relevant to the Gribov problem.

有效局部 QCD 计算和 Gribov 复制问题

标准的函数操作已被证明暗示了 QCD 的费米子格林函数满足的显着特性，并被称为有效局部性。由于规范场自由度的全规范不变求和，有效局部性是 QCD 的非微扰特性。这一出乎意料的结果让人怀疑著名的 Gribov 复制问题在某种程度上被忽视了。有人认为事实并非如此。分析是在与 Gribov 问题相关的强耦合极限下进行的。
