Dynamics of Multiparticle Systems with non - Abelian Symmetry

We consider the dynamics governing the evolution of a many body system constrained by an nonabelian local symmetry. We obtain explicit forms of the global macroscopic condition assuring that at the microscopic level the evolution respects the overall symmetry constraint. We demonstrate the constraint mechanisms for the case of SU(2) system comprising particles in fundamental, and adjoint representations (`nucleons' and `pions').

J/Psi suppression in an expanding equilibrium hadron gas

We consider an ideal gas of massive hadrons in thermal and chemical equilibrium. The finite-size gas expands longitudinally in accordance with Bjorken law. Also the transverse expansion in a form of the rarefaction wave is considered. We show that J/Psi suppression in such an environment, when combined with the disintegration in nuclear matter, agrees qualitatively well with NA38 and NA50 data.

Properties of an equilibrium hadron gas subjected to the adiabatic longitudinal expansion

We consider an ideal gas of massive hadrons in thermal and chemical equilibrium. The gas expands longitudinally in an adiabatic way. This evolution for a baryonless gas reduces to a hydrodynamic expansion. Cooling process is parametrized by the sound velocity. The sound velocity is temperature dependent and is strongly influenced by hadron mass spectrum.
