Universal behaviour of the SU(2) running coupling constant in the continuum limit
Marco Guagnelli (for the ALPHA Collaboration)🇮🇹
Abstract
We present data from the ALPHA Collaboration about lattice calculation of SU(2) pure--gauge running coupling constant, obtained with two different definitions of the coupling itself, which show universality of the continuum limit and clarify the applicability of renormalized perturbation theory.
