Gauge action improvement and smearing
نویسنده
چکیده
The effect of repeatedly smearing SU(3) gauge configurations is investigated. Six gauge actions (Wilson, Symanzik, Iwasaki, DBW2, Beinlich-Karsch-Laermann, Langfeld) and three smearing recipes (APE, HYP, EXP, the first two with and without projection) are compared. The impact on Wilson loops and the Creutz ratio is monitored as well as the “naive” topological charge. In the latter case improved actions benefit most impressively.

Perturbative determination of cSW with Symanzik improved gauge action and stout smearing
We determine the improvement factor cSW in one-loop lattice perturbation theory for the plaquette and Symanzik improved gauge actions. The fermionic action is O(a) clover improved with onetime stout smearing. cSW is derived from the one-loop correction to the quark-quark-gluon vertex in the off-shell regime. We give a first numerical value for the one-loop contribution to the non gauge-invarian...
متن کاملCooling , smearing and Dirac eigenmodes - A comparison of filtering methods in lattice gauge theory a
Starting from thermalized quenched SU(2) configurations we apply cooling or iterated smearing, respectively, to produce sequences of gauge configurations with less and less fluctuations. We compute the low lying spectrum and eigenmodes of the lattice Dirac operator and compare them for the two types of smoothing. Many characteristic properties of the eigensystem remain invariant for all configu...

We present an investigation of gauge invariant smearing for Wilson fermions on a 24 × 48 lattice at β = 6.2. We demonstrate a smearing algorithm that allows a substantial improvement in the determination of the baryon spectrum obtained using propagators smeared at both source and sink, at only a small computational cost. We investigate the matrix of correlators constructed from local and smeare...
متن کاملTests of Improved Kogut-Susskind Fermion Actions
Improvements of the Kogut-Susskind quark action may allow extraction of continuum physics from coarser lattices than would be required with the simplest formulation. This is especially important for full QCD simulations, which are much more time consuming than quenched calculations. Improvement of the rotational symmetry and the dispersion relation can be achieved by introducing the Naik term, ...
متن کاملPerturbative renormalisation of quark bilinear operators for overlap fermions with and without stout links and improved gauge action
We calculate lattice renormalisation constants of local and one-link quark operators for overlap fermions and improved gauge actions in one-loop perturbation theory. For the local operators we stout smear the SU(3) links in the fermionic action. Using the popular tadpole improved Lüscher-Weisz actions at β = 8.45 and β = 8.0 we present numerical values for the Z factors in the MS scheme (partly...
