Lattice Perturbation Theory by Computer Algebra : A Three - Loop Result for the Topological Susceptibility

Abstract

We present a scheme for the analytic computation of renormalization functions on the lattice, using a symbolic manipulation computer language. Our first nontrivial application is a new three-loop result for the topological susceptibility.
