A general method for nonperturbative renormalization of lattice operators
Abstract
We propose a nonperturbative method for computing the renormalization constants of generic composite operators. This method is intended to reduce some systematic errors, which are present when one tries to obtain physical predictions from the matrix elements of lattice operators. We also present the results of a calculation of the renormalization constants of several twofermion operators, obtained, with our method, by numerical simulation of QCD, on a 16 ^{3}x 32 lattice, at β = 6.0. The results of this simulation are encouraging, and further applications to fourfermion operators and to the heavy quark effective theory are proposed.
