Symanzik Improvement In The Static Quark Potential

A systematic investigation of Symanzik improvement in the gauge field action is performed for the static quark potential in quenched QCD. We consider Symanzik improved gauge field configurations on a 16 × 32 lattice with a relatively coarse lattice spacing of 0.165(2) fm. A matched set of Standard Wilson gauge configurations is prepared at β = 5.74 with the same physical volume and lattice spac...

The static quark potential in full QCD ∗

We report results on the static quark potential in two-flavor full QCD. The calculation is performed for three values of lattice spacing a 3 ×48 lattices respectively, at sea quark masses corresponding to mπ/mρ ≈ 0.8–0.6. An RG-improved gauge action and a tadpole-improved SW clover quark action are employed. We discuss scaling of mρ/ √ σ and effects of dynamical quarks on the potential.

Static quark-antiquark potential in the quark-gluon plasma from lattice QCD.

We present a state-of-the-art determination of the complex valued static quark-antiquark potential at phenomenologically relevant temperatures around the deconfinement phase transition. Its values are obtained from nonperturbative lattice QCD simulations using spectral functions extracted via a novel Bayesian inference prescription. We find that the real part, both in a gluonic medium, as well ...

Towards String Breaking In The Static Quark Potential

Techniques for revealing the ground state of the static quark potential at large separations are presented and evaluated. The static quark potential is calculated on both unimproved and improved lattice gauge field configurations. Both lattices are 16 ×32 and have approximately the same lattice spacing (≈ 0.18 fm). We show that using an improved gluon action not only gives better rotational sym...

Analytic Invariant Charge and the Lattice Static Quark–antiquark Potential

A recently developed model for the QCD analytic invariant charge is compared with quenched lattice simulation data on the static quark–antiquark potential. By employing this strong running coupling one is able to obtain the confining quark–antiquark potential in the framework of the one–gluon exchange model. To achieve this objective a technique for evaluating the integrals of a required form i...
