Low-mass dielectron measurements in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC

Sumario:Dielectrons are an excellent probe for the QCD matter created in created in ultra-relativistic heavy-ion collisions, since they are emitted during the whole evolution of the collision and do not interact strongly with the medium. To isolate the QGP signals, measurement of the dielectron production in vacuum and its modifications due to the presence of cold nuclear matter is necessary. We present and discuss results from a low magnetic field detector setup in proton-proton collisions at s=13TeV , as well as the measurement of dielectron production in pp, p–Pb, and Pb–Pb collisions at sNN=5TeV .
