Production of Low Mass Dielectrons in Pb-Pb collisions with ALICE — •Christoph Baumann — Goethe-Universität Frankfurt

The measurement of low mass dielectrons allows probing all stages of ultra-relativistic collisions as electrons do not suffer from final state interactions. This enables the search for thermal radiation of the hot and dense medium created in heavy-ion collisions at LHC. We will present the status of the dielectron measurements in Pb-Pb collisions at √s_NN= 2.76 TeV with ALICE, focussing on the search for thermal radiation, via the study of a possible dielectron enhancement at low masses. The status and perspectives of dielectron analyses in pp and p-Pb will also be discussed.
