Low mass dilepton production at ultrarelativistic energies
Dilepton production in pp and Au+Au nucleus-nucleus collisions at √ s = 200 GeV as well as in In+In and Pb+Au at 158 A·GeV is studied within the microscopic HSD transport approach. A comparison to the data from the PHENIX Collaboration at RHIC shows that standard in-medium effects of the ρ, ω vector mesons compatible with the NA60 data for In+ In at 158 A·GeV and the CERES data for Pb+Au at 158...
متن کاملDilepton production at SIS energies
In this short review the results of detailed studies for dilepton production from p + A and A + A reactions at SIS energies are presented. The calculations are based on a semi-classical BUU transport model that includes the off-shell propagation of vector mesons and evaluates the width of the vector mesons dynamically. Different scenarios of in-medium modifications of vector mesons, such as col...
متن کاملDilepton production in ultrarelativistic heavy-ion collisions.
Many probes have been proposed to map out the behaviour of hot and dense hadronic matter and also to highlight its eventual transition to a plasma of quarks and gluons. It is outside the scope of this talk to review them all or even partially: we will concentrate on electromagnetic radiation and more specifically on the emission of thermal lepton pairs. Those suffer minimal final state interact...
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 production in neutron-proton collisions at HADES energies∗
Experiments with High Acceptance Di-electron Spectrometer (HADES) are aimed at searching for medium modifications of hadrons at moderately high temperatures (T < 100 MeV) and baryonic densities up to 3 times the normal nuclear matter density. Due to negligible final state interactions with surrounding medium, dileptons provide a very clean and powerful probe for this purpose. Dilepton productio...
