Domain Wall Fermion Study of Scaling in Non-perturbative Renormalization of Quark Bilinears and $B_K$

We compute non--perturbatively the renormalization coefficients of scalar and pseudoscalar operators, local vector and axial currents, conserved vector and axial currents, and $O_{LL}^{ΔS=2}$ 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.

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 $O^{ΔS=2}_{LL}$ 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.
