Within the framework of Tsallis statistics with q ~ 1, we construct aperturbation theory for treating relativistic quantum field systems. We findthat there appear initial correlations, which do not exist in theBoltzmann-Gibbs statistics. Applying this framework to a quark-gluon plasma, wefind that the so-called thermal masses of quarks and gluons are smaller than inthe case of Boltzmann-Gibbs statistics.Comment: 16 pages, no figure
