title

Domain Wall Fermion Study of Non-perturbative Renormalization of Quark Bilinears with Scaling

collaboration

abstract

We compute non--perturbatively the renormalization of quark bilinears
and extract $Z_A$, $Z_V$, $Z_P$, $Z_S$ over a wide range of energy
scales using a scaling technique that connects the results of
simulations at different values of coupling $\beta$. We use the domain
wall fermion formulation in 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. These calculations involve both the
local and the conserved vector and axial
currents available in the domain wall formulation.
