The influence of nucleon--nucleon collisions on the filamentation instability in a hadronic plasma

The relativistic kinetic model with mean fields is used to study the effect of intraflux NN collisions and a baryon-resonance admixture on the filamentation instability in a hadronic plasma, which can develop in relativistic nucleus--nucleus collisions during the mutual-penetration stage. The τ approximation is used for the collision integrals. A general dispersion equation is derived, which determines the eigenfrequencies of the two-flux nuclear system. It is found that the increment of the filamentation instability is practically independent of the intensity of intraflux collisions. The inclusion of Δ isobars decreases the increment by no more than 10%. The effect of higher baryon resonances is estimated
