Query: Melting rho Meson and Thermal Dileptons   We give a brief survey of theoretical evaluations of light vector mesons in
hadronic matter, focusing on results from hadronic many-body theory. We
emphasize the importance of imposing model constraints in obtaining reliable
results for the in-medium spectral densities. The latter are subsequently
applied to the calculation of dilepton spectra in high-energy heavy-ion
collisions, with comparisons to recent NA60 data at the CERN-SPS. We discuss
aspects of space-time evolution models and the decomposition of the excess
spectra into different emission sources.
