Creutz比率的反向运行或不运行
Backward running or absence of running from Creutz ratios
摘要：
在SU（2）格点规范理论中，我们利用两个狄拉克费米子在伴随表象中的克罗伊茨比提取了运行耦合。根据如何外推到零费米子质量进行，无论是向后运行或运行的情况下观察到强裸耦合。这一行为与其他表明该理论存在红外不动点的发现是一致的。
英文摘要：
We extract the running coupling based on Creutz ratios in SU(2) lattice gauge theory with two Dirac fermions in the adjoint representation. Depending on how the extrapolation to zero fermion mass is performed, either backward running or an absence of running is observed at strong bare coupling. This behavior is consistent with other findings which indicate that this theory has an infrared fixed point.
