摘要:Inter-quark potentials at nite temperature are derived from Nambu-Bethe-Salpeter (NBS) amplitudes. Employing the formalism developed by Laine et al. and Beraudo et al., we calculate the Q¯Q potentials with nite quark masses in imaginary-time. The extracted potentials show Coulomb plus linear behavior, and have moderate temperature dependence below Tc. On the other hand, the potential considerably changes and becomes at at long distance above Tc. 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.
