Successful application of a two-exponent ansatz to model the potential.

Insights into the confinement phase behavior of heavy quarks in finite-temperature QCD.

Abstract

Results of the study of lattice QCD with two flavors of nonperturbatively improved Wilson fermions at finite temperature are presented. The transition temperature for m_{\pi}/m_{\rho} \sim 0.8 and lattice spacing a \sim 0.12 fm is determined. A two-exponent ansatz is successfully applied to describe the heavy quark potential in the confinement phase.
