On formation of equation of state of evolving quantum field
Abstract
Stylized model of evolution of matter created in ultrarelativistic heavy ion collisions is considered. Systematic procedure of computing quantum corrections in the framework of Keldysh formalism is formulated. Analytical expressions for formation of equations of state taking into account leading quantum corrections are worked out, complete description of subleading corrections and analytical expressions for some of them are presented.
