Within the framework of Tsallis statistics with q 1, we construct a perturbation theory for treating relativistic quantum field systems. We find that there appear initial correlations, which do not exist in the Boltzmann-Gibbs statistics. Applying this framework to a quark-gluon plasma, we find that the so-called thermal masses of quarks and gluons are smaller than in the case of Boltzmann-Gibbs statistics. It is expected that a quark-gluon plasma will soon be produced in ultrarelativistic heavy-ion collision experiments at the BNL Relativistic Heavy Ion Collider (RHIC). The CERN Large Hadron Collider (LHC) will also soon be ready for experiments. A few observations regarding quark-gluon plasmas are in order.
