### Abstract

We formulate the renormalization group equation for Wilson loops in such a way as to make the analogy with spin systems more tranparent. We thus obtain a quantity ζ(g^{2}) analogous to the anomalous dimension γ(g^{2}) for spin systems. The value of ζ(g^{2}) at the non-trivial fixed point in 4 + ε{lunate} dimensions gives the exponent η defined by Peskin.
