再看朗道规范三胶子顶点

Another look at the Landau gauge three-gluon vertex

Guilherme T. R. Catumba, Orlando Oliveira, Paulo J. Silva

摘要:

我们使用大物理体积的$\sim$(6.5 fm)$^ 4$和$\sim$(8 fm)$^ 4$和大统计系综的格格点量子色动力学模拟重新计算了朗道规范中的三胶子顶点。对于所分析的运动学配置,其由唯一的形状因子描述,还执行晶格伪影的评估。特别注意的是,低能量的行为顶点和它的连接与证据(或缺乏它)的红外鬼占主导地位。

英文摘要:

We revisit the computation of the three-gluon vertex in the Landau gauge using lattice QCD simulations with large physical volumes of $\sim$ (6.5 fm)$^ 4$ and $\sim$ (8 fm)$^ 4$ and large statistical ensembles. For the kinematical configuration analysed, that is described by a unique form factor, an evaluation of the lattice artefacts is also performed. Particular attention is given to the low energy behaviour of vertex and its connection with evidence (or lack of it) of infrared ghost dominance.
