Abstract

Inter-quark potentials at finite temperature are derived from Nambu-Bethe-Salpeter (NBS) amplitudes. Employing the formalism developed by Laine et al. and Beraudo et al., we calculate the QQ ^¯ potentials with finite quark masses in imaginary-time. The extracted potentials show Coulomb plus linear behavior, and have moderate temperature dependence below T_c. On the other hand, the potential considerably changes and becomes flat at long distance above T_c. Although our potential is obtained in imaginary-time, it is expected that the obtained potential is a natural extension of potentials from the Polyakov loop correlations.
