The renormalization group equation for the Wilson loop

Alan J. McKane, Michael Stone

Research output: Contribution to journalArticle


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(g2) analogous to the anomalous dimension γ(g2) for spin systems. The value of ζ(g2) at the non-trivial fixed point in 4 + ε{lunate} dimensions gives the exponent η defined by Peskin.
