AbstractAbstract
[en] We point out since the Wilson loop is a renormalization group invariant it has a remarkably simple rescaling law, in which loops of decreasing length and fixed coupling constant are identical to those with fixed length but with a running coupling constant. We also give an argument on how this rescaling law might be used to deduce the sometimes adopted notion of confinement, namely the running coupling constant behaves like g2(k2) approximately 1/k2 in the infrared limit k2→0.
