Dilepton Spectroscopy of QCD Matter at Collider Energies
Dilepton Spectroscopy of QCD Matter at Collider Energies
Low-mass dilepton spectra as measured in high-energy heavy-ion collisions are a unique tool to obtain spectroscopic information about the strongly interacting medium produced in these reactions. Specifically, in-medium modifications of the vector spectral function, which is well known in the vacuum, can be deduced from the thermal radiation off the …
