Transport Coe cients of Quark-Gluon Plasma Within the Quasiparticle Model

The analysis of experimental data obtained in heavy ion collisions at RHIC and LHC showed that the evolution of the QGP is well described by nearly ideal hydrodynamics [1]. Nevertheless, we deal with the relativistic viscous hydrodynamics, which is characterized by the transport coe cients, for example, the shear η and bulk ζ viscosities. Those are the parameters that quantify dissipative processes in the hydrodynamic evolution of a uid. Their values and properties not only carry information on how far the system appears from an ideal hydrodynamics but also provide a relevant insight into the uid dynamics and its critical phenomena [2].
