Domain Wall Fermion Study of Scaling in Non-perturbative Renormalization of Quark Composite Operators

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