Abstract
The physical mass scales that determine the behaviour of general (simply-laced) Homogeneous Sine-Gordon models are investigated by means of a study of their finite-size effects, using the thermodynamic Bethe ansatz. These models describe integrable multiparameter perturbations of the theory of level- -parafermions, where is a Lie group. The parameters can be related to adjustable mass scales of stable and unstable particles. Our results confirm the presence of unstable particle states at generic values of , as predicted at large by semiclassical arguments.
