摘要
We study the properties of quark-antiquark interactions in the Quark-Gluon Plasma at moderate temperatures, T similar or equal to 1-2 T-c,within a Brueckner-type many-body approach. The quark-antiquark T-matrix, including both color-singlet and -octet channels, and corresponding quark self-energies are evaluated self-consistently. We find that light mesonic states persist as resonances in the Quark-Gluon Plasma up to temperatures T similar or equal to 1.75T(c) and fermionic quasiparticles acquire masses of up to similar to 150MeV and widths of around similar to 200MeV.
