Kinetics of the chiral phase transition — •Hendrik van Hees1,2, Christian Wesp1, Alex Meistrenko1, and Carsten Greiner11Johann-Wolfgang-Goethe-Universität Frankfurt, Institut für theoretische Physik, Max-von-Laue-Str. 1, D-60438 Frankfurt — 2Frankfurt Institute for Advanced Studies (FIAS), Ruth-Moufang-Str. 1, D-60438 Frankfurt

We simulate the kinetics of the chiral phase transition in hot and dense strongly interacting matter within a novel kinetic-theory approach. Employing an effective linear σ model for quarks, σ mesons, and pions we treat the quarks within a test-particle ansatz for solving the Boltzmann transport equation and the mesons in terms of classical fields. The decay-recombination processes like σ ↔ q+q are treated using a kind of wave-particle dualism using the exact conservation of energy and momentum. After demonstrating the correct thermodynamic limit for particles and fields in a “box calculation” we apply the simulation to the dynamics of an expanding fireball similar to the medium created in ultrarelativistic heavy-ion collisions.
