Nonperturbative dynamics of an expanding flux-tube in the theory of heavy ion collisions

The considered variant of the flux-tube model is based on the joint action of the same mechanisms of the vacuum particle creation as the standard Schwinger mechanism and the Casimir effect. It is assumed that pre-equilibrium quark-gluon plasma (QGP) is created in ultrarelativistic heavy-ion collision. According to the considered model, these two mechanisms act at different time scales and lead to qualitatively different momentum distributions.
