Seminar “THEORY OF HADRONIC MATTER UNDER EXTREME CONDITIONS” 11 February 2015, 16:00, BLTP Blokhintsev hall (4th floor)

Genis Musulmanbekov (LIT JINR) “On Production and Polarization of Hyperons in Heavy Ion Collisions. Continuation” Abstract We discuss a schematic model describing the evolution of matter created in ultrarelativistic heavy-ion collisions. We employ the Keldysh formalism in order to describe the relaxation of a quantum field from the initial, highly excited state. For the case of a homogeneous scalar field we show the emergence of the equation of state explicitly. We present a complete description of subleading corrections and discuss analytical expressions for some of them.
