Interpretation of Recent SPS Dilepton Data
We summarize our current theoretical understanding of in-medium properties of the electromagnetic current correlator in view of recent dimuon data from the NA60 experiment in In(158 AGeV)-In collisions at the CERN-SPS. We discuss the sensitivity of the results to space-time evolution models for the hot and dense partonic and hadronic medium created in relativistic heavy-ion collisions and the c...
متن کاملA coarse-graining approach for dilepton production at SPS energies
Coarse-grained output from transport calculations is used to determine thermal dilepton emission rates by applying medium-modified spectral functions from thermal quantum field theoretical models. By averaging over an ensemble of events generated with the UrQMD transport model, we extract the local thermodynamic properties at each time step of the calculation. With an equation of state the temp...
متن کاملDilepton signals in heavy ion collisions at the CERN SPS
This paper overviews the main results on dilepton and heavy flavour production in heavy ion collisions, obtained in measurements done at the CERN SPS, over the last few years. The presently available results are very interesting, indicating the production of a new state of matter in central Pb-Pb collisions at SPS energies. However, important questions remain open. New and improved measurements...
متن کاملPion Interferometry: Recent results from SPS
Recent HBT results from the CERES experiment at the SPS are reviewed. Emphasis is put on the centrality and beam energy dependence, and the results are put into perspective with results at lower and higher beam energies. The rather weak beam energy dependence of the HBT radii may be understood in terms of a transition from baryon to pion dominated freeze-out. The observed short lifetimes and em...
متن کاملComprehensive Interpretation of Thermal Dileptons at the SPS
Employing thermal dilepton rates based on a medium-modified electromagnetic correlation function we show that recent dimuon spectra of the NA60 collaboration in central In-In collisions at the CERN-SPS can be understood in terms of radiation from a hot and dense hadronic medium. Earlier calculated in-medium ρ-meson spectral functions provide an accurate description of the data up to dimuon inva...
