Production of Low Mass Dielectrons in Pb-Pb collisions at ALICE — •Christoph Baumann — Goethe-Universität Frankfurt
The measurement of low mass dielectrons allows to probe all stages of ultra-relativistic collision because electrons do not undergo strong interactions. Thus the search for thermal signatures of a hot and dense medium created in heavy-ion collisions at LHC becomes possible. We will present the status of such measurements in Pb-Pb collisions with ALICE at √sNN= 2.76 TeV and discuss possible thermal signatures, especially the search for an enhanced production of virtual photons.
