TL;DR
This paper reports on the calculation of improvement and renormalization constants in O(a) improved lattice QCD at specific beta values, using Ward identities to analyze operator properties.
Contribution
It provides new determinations of renormalization constants and improvement coefficients in lattice QCD at beta=6.0 and 6.2, including mass dependence and equation of motion operator coefficients.
Findings
Renormalization constants for bilinear operators determined at two beta values.
Mass dependence of renormalization constants analyzed.
Coefficients of equation of motion operators extracted.
Abstract
We present results at beta=6.0 and 6.2 for the O(a) improvement and renormalization constants for bilinear operators using axial and vector Ward identities. We discuss the extraction of the mass dependence of the renormalization constants and the coefficients of the equation of motion operators.
