Parallel Session: Improvement and Renormalization I

Tuesday June 29th, 14.50 - 15.10, Room B

Non-perturbative renormalization of the non-singlet operator using the Schroedinger Functional

Abstract: We compute non-perturbatively the running of the renormalization constant for the average momentum of the non-singlet operator as appearing in the Wilson operator product expansion. We show that the continuum values of this renormalization constant are universal with respect to the lattice action used. Our data allow us to calculate a renormalization group invariant renormalization constant which can be used to renormalize physical matrix elements in an arbritray renormalization scheme at a desired scale.
