Scaling Analysis of Improved Actions for Pure SU(3) Gauge Theory
arXiv:hep-lat/9809086 · doi:10.1016/S0920-5632(99)85246-3
Abstract
We have explored the behaviour of some improved actions based on a nonperturbative renormalization group (RG) analysis in coupling space. We calculate the RG flow in two-coupling space $(\boneone,\bonetwo)$ and examine the restoration of rotational invariance and the scaling of physical quantities .
