Studies of the hydrodynamic evolution of matter produced in fluctuations inp¯pcollisions and in ultrarelativistic nuclear collisions

摘要: In this first paper of a series two, we present comprehensive study the hydrodynamic evolution matter produced in central region ultrarelativistic heavy-ion collisions and high-multiplicity fluctuations p-barp-italic collisions. We shall begin with discussion limits applicability perfect-fluid description high-energy A simple bag-model equation state is argued to have qualitative semiquantitative features expected from lattice gauge theory theoretical understanding. also discuss boundary conditions for equations, what classes events would correspond initial conditions. The decoupling at low energy density methods computing transverse-momentum distributions hadrons are analyzed. finally details computer code which use numerically solve equations.
