| contents | The present thesis is devoted to the study of some of the features of the deconfined state of matter dubbed Quark-Gluon Plasma (QGP). The different properties of the extreme matter that have been studied in this thesis are next-to-leading order dispersion properties for soft-moving quarks, screening masses of mesons, drag and diffusion properties of heavy quarks, the specific shear viscosity of QGP and energy loss of heavy quarks propagating in QGP background. The theoretical techniques which are utilized in order to study these properties are mainly hard thermal loop effective theory, which is required when one is interested in studying the soft scale physics of the underlined theory QCD at finite temperatures, and the other techniques, which are utilized here is the nonperturbative resummation approach dubbed as Gribov quantization. This nonperturbative resummation deals with the magnetic scale of the theory through the Gribov mass parameter. |
