A method for getting a finite $$\alpha $$ α in the IR region from an all-order beta function
Abstract 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 $$N=1$$ N = 1 supersymmetric gauge theories. In the approach presented here, the running cou...
