Theoretical Review on QCD and Vector Mesons in Dileptonic Quark Gluon Plasma (1208.4437v3)

Abstract: After the discovery of the Quantum Chromodynamics (QCD), many experimental and theoretical efforts have been made to investigate physics issues involved in ultra relativistic heavy-ion collisions. The fundamental goal of this work is to present a short guide of the underlying theory of strong interactions with emphasis on the light vector mesons based on the exceptional work of R.Rapp and J.Wambach. Today widely believed that deconfinement and chiral symmetry restoration probably takes place in a hot and dense hadronic medium as this produced at these collisions. We focus at the place where the examination of the new form of matter, so-called Quark Gluon Plasma (QGP), can be done through the investigation of the dileptonic production coming from light vector mesons. Significant progress has been made since the last years, but still some open questions remain at the non-perturbative mass region.
