Power corrections in the quarkantiquark potential at finite temperature
Abstract
A recently proposed phenomenological model, which includes nonperturbative effects from dimension two gluon condensates, is applied to analyze the available lattice data for the heavy quark free energy in the deconfined phase of quenched QCD. For large qq separations, we recover previous results for the Polyakov loop, exhibiting unequivocal power corrections in the temperature. For the qq potential at finite temperature and finite separation, we find that a good overall description of the lattice data can be achieved once the condensate is properly accounted for. In addition, the model predicts a duality between the zero temperature potential as a function of the qq separation, on the one hand, and the quark selfenergy as a function of the temperature, on the other, which turns out to be satisfied to a high degree by the lattice data.

We study the string tension as a function of temperature, fitting the SU(3) lattice QCD finite temperature free energy potentials computed by the Bielefeld group. We compare the string tension points with order parameter curves of ferromagnets, superconductors, or string models, all related to confinement. We also compare the SU(3) string tension with the one of SU(2) lattice QCD. With the curve providing the best fit to the finite temperature string tensions, the spontaneous magnetization curve, we then show how to include finite temperature, in the state of the art confining and chiral invariant quark models.

Static quarkantiquark interactions in zero and finite temperature QCD: I. Heavy quark free energies, running coupling, and quarkonium binding
We analyze heavy quark free energies in 2flavor QCD at finite temperature and the corresponding heavy quark potential at zero temperature. Static quarkantiquark sources in color singlet, octet and color averaged channels are used to probe thermal modifications of the medium. The temperature dependence of the running coupling, {alpha}{sub qq}(r,T), is analyzed at short and large distances and is compared to zero temperature as well as quenched calculations. In part, we also compare our results to recent findings in 3flavor QCD. We find that the characteristic length scale below which the running coupling shows almost no temperature dependence is almostmore » 
Static quarkantiquark potential: Scaling behavior and finitesize effects in SU(3) lattice gauge theory
We present results on the static {ital q{bar q}} potential from highstatistics simulations on 16{sup 4}, 24{sup 3}{times}32, and 32{sup 4} lattices, using the standard Wilson action at {beta}=6.0, 6.2, and 6.4 on the Connection Machine CM2. To decrease noise and increase accuracy, we applied a suitable local smoothing technique on the spatial parts of Wilson loop operators. As a result, we find a violation of asymptotic scaling of the string tension, as signaled by {radical}{sigma} /{Lambda}{sub {ital L}}=96.7(1.6)(2.6), 86.4(1.0)(1.9), 82.3(0.8)(1.7), for the three {beta} values, with statistical and systematic errors. We observe a linear confining potential up to distancesmore » 
Static quarkantiquark free energy and the running coupling at finite temperature
We analyze the free energy of a static quarkantiquark pair in quenched QCD at short and large distances. From this we deduce running couplings, g{sup 2} (r, T), and determine the length scale that separates at high temperature the short distance perturbative regime from the large distance nonperturbative regime in the QCD plasma phase. Ambiguities in the definition of a coupling beyond the perturbative regime are discussed in their relation to phenomenological considerations on heavy quark bound states in the quark gluon plasma. Our analysis suggests that it is more appropriate to characterize the nonperturbative properties of the QCD plasmamore »
