Abstract:
"... the research line developed in this dissertation will take two roads. First, the photon emission rate and the electrical conductivity of the QGP will be calculated at finite temperature and finite chemical potential using AdS/QCD approximations. To do so, we supposed the medium properties to be encoded in the energy momentum tensor of the geometric background. The results obtained in the hard wall and soft wall models are in consistency with the observed phenomenology and they are also in agreement with other holographic, results, as the D3/D7 or the Sakai Sugimoto models, suggesting the universality of AdS/CFT conjecture as tool to explore QCD. Second, by changing the position of the conformal boundary, new extensions to the AdS/QCD models can be constructed in order to calculate mass spectra and decay constants of vector heavy mesons organized in Regge trajectories ..."
