A method for getting a finite α in the IR region from an all-order beta function

The analytical method of the QCD running coupling constant is extended to a model with an all-order beta function which is inspired by the famous Novikov–Shifman–Vainshtein–Zakharov beta function of N = 1 supersymmetric gauge theories. In the approach presented here, the running coupling is determin...
