摘要：The topology conserving gauge action proposed by Lüscher is expected to reduce the number of
non-smooth gauge configurations as well as the topology change compared to the conventional
actions for the same lattice spacings. We report our quenched QCD study of the topological
stability and the scaling violation of the static quark potential. We find that the the topology
change is indeed suppressed when the parameter e is of order one. We also find that the scaling
violation in the static quark potential remain reasonably small in the parameter range of our study.
Our study is done at the inverse lattice spacing a−1 = 1.4–2.5 GeV with the lattice size L = 1.0–
1.6 fm.
