论文摘要
我们报告了我们正在进行的非扰动计算的一些初步结果，该计算使用梯度流以定义耦合和阶梯缩放技术来计算它。对于计算，我们考虑了四个维度的纯量规SU（3）理论，该理论在单个平面中具有扭曲的边界条件的晶格上定义，并将耦合的能量标度与有效尺寸相结合，结合了圆环的大小和仪表组的尺寸。此外，我们探讨了拓扑冻结对耦合计算的一些影响。
We report some preliminary results of our ongoing non-perturbative computation of the twisted 't Hooft running coupling in a particular set-up, using the gradient flow to define the coupling and step scaling techniques to compute it. For the computation we considered a pure gauge SU(3) theory in four dimensions, defined on the lattice on an asymmetrical torus endowed with twisted boundary conditions in a single plane, and related the energy scale of the coupling to an effective size combining the size of the torus and the rank of the gauge group. Additionally, we explore some of the effects of the freezing of the topology on the computation of the coupling.
