Domain wall fermion study of scaling in non-perturbative renormalization of quark composite operators

We compute non-perturbatively the renormalization coefficients of scalar an d pseudoscalar operators, local vector and axial currents, conserved vector and axial currents, and O-LL(DeltaS=2) over a wide range of energy scales using a scaling technique that connects the results of simulations at diffe rent values of coupling beta. We use the domain wall fermion formulation in the quenched approximation at a series of three values of beta = 6.0, 6.45 , 7.05 corresponding to lattice spacing scaling by factors of two.
