The thermodynamic Bethe ansatz method is employed for the study of the integrable critical RSOS(q1, q2; q) model. The high and low temperature behavior are investigated, and the central charge of the effective conformal field theory is derived.

The ln 2 s behaviour of total cross sections, first obtained by Heisenberg 50 years ago, receives now increased interest both on phenomenological and theoretical levels. In this paper we present a modification of the Heisenberg's model in connection with the presence of glueballs and we show that it leads to a realistic description of all existing hadron total cross-sections data.
