标题： Constraining the gauge-fixed Lagrangian in minimal Landau gauge

摘要： 连续体规范固定公式以解决Gribov-Singer歧义仍然是一个挑战。 在数值格点计算中，找到操作性解决方案的拉格朗日公式，如最小朗道规范，是一种可能性。 这种公式将通过重构迪森-施温格方程来约束，其中格点最小朗道规范的鬼 propagator 是一个解。 发现这需要一个额外的项。 作为副产品，获得了三维和四维中鬼-胶子顶点的新的高精度格点结果。 显示英文摘要

摘要： A continuum formulation of gauge-fixing resolving the Gribov-Singer ambiguity remains a challenge. Finding a Lagrangian formulation of operational resolutions in numerical lattice calculations, like minimal Landau gauge, would be one possibility. Such a formulation will here be constrained by reconstructing the Dyson-Schwinger equation for which the lattice minimal-Landau-gauge ghost propagator is a solution. It is found that this requires an additional term. As a by-product new, high precision lattice results for the ghost-gluon vertex in three and four dimensions are obtained.
