Fixed Point SU(3) Gauge Actions: Scaling Properties and Glueballs

High Energy Physics - Lattice 2009-10-31 v1

Abstract

We present a new parametrization of a SU(3) fixed point (FP) gauge action using smeared ("fat") gauge links. We report on the scaling behaviour of the FP action on coarse lattices by means of the static quark-antiquark potential, the hadronic scale r0r_0, the string tension σ\sigma and the critical temperature TcT_c of the deconfining phase transition. In addition, we investigate the low lying glueball masses where we observe no scaling violations within the statistical errors.
