abstract

Results for renormalization constants using quarks as external states
in Landau gauge are presented at beta=6.4. We discuss discretization
errors in this calculation.

TITLE: CLASSICALLY PERFECT ACTION FOR SU(3) GAUGE THEORY

Authors: Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee

Abstract: The derivation of the classical perfect action for SU(3) using the
square root 3 blocking transformation is presented. Numerical
results using an action truncated to the quadratic order are discussed
as a function of the lattice size and the tuning parameter in the
blocking transformation. Our final results are presented in terms of
a minimal set of small Wilson loops.
