Probing spectral properties of hadrons in hot and dense matter

	In-medium spectral properties of ρ and ω mesons from one-loop self-energy at finite temperature and density will be presented. Within the framework of real time thermal field theory, the imaginary part of the self-energy derived from its discontinuities will be discussed. An extensive set of spin one-half and three-half 4-star resonances in the baryonic loops will be considered with the full relativistic baryon propagator in the loop diagrams in addition to the mesonic loops. The integrated dilepton yield, after space-time evolution in relativistic hydrodynamics with quark gluon plasma in the initial state, will be shown to be in good agreement with the experimental data obtained by the NA60 Collaboration for In-In collisions at the CERN/SPS energy.
