Description
We develop a kinetic equation approach to nonequilibrium pion and sigma meson production in a time-dependent, chiral symmetry breaking field (inertial mechanism) We investigate the question to what extent the low-momentum pion enhancement observed in heavy- ion collisions at CERN - LHC can be addressed within this formalism. In this preliminary study, we consider the inertial mechanism for nonequilibrium production of sigma-mesons and their simultaneous decay into pion pairs. The resulting pion distribution shows a low-momentum enhancement.
