Resumo

Relativistic dissipative hydrodynamics has become the most important theoretical tool to model the evolution of the strongly-coupled quark-gluon plasma (QGP) created in heavy-ion collisions. In recent years, there have been enormous advances in this _eld, such as the development of a complete hydrodynamic theory including second-order velocity gradients which is very successful in modelling QGP dynamics. However, there are certain phenomena being currently observed at the Relativistic Heavy Ion Collider (RHIC) which seem to require hydrodynamic theories going beyond second order gradients. Conical ow and the di_usion wake induced by the passage of a quenched part on through the plasma, as well as the evolution of initial state uctuations, are examples of such phenomena. The purpose of this project is to study these e_ects using an hydrodynamic approach, in order to determine the inuence of higher-order velocity gradients and nonlinear terms in the evolution of these e_ects and their related observables, in the background of the expanding dissipative QGP.
