Thermodynamics of relativistic composite systems

The author investigates a gas of composite constituents consisting of relativistic interacting two-particle systems. In particular, he explicitly considers here only certain systems with a special form for the pair-interactions. For this gas he proceeds to formulate the statistical mechanics using the relativistic constraint formalism with the Faddeev phase space measure. Thus through this approach he is able to evaluate analytically the partition function for this kind of interaction. Finally he suggests the possible application of these models to a gas of hadrons (mesons) built up from quark constituents. (Auth.)
