Research Abstract

Using effective models of hadrons, I studied, e.g., how the changes of hadron properties affect to physical observables at finite temperature and/or density. And I found e.g., that the effect of mixing between the vector and axial-vector mesons gives a broadening effect to the di-lepton spectrum. For making a new way of the analysis, I proposed a way to relate holographic QCD (hQCD) models to the model based on the hidden local symmetry.
