Abstract

Dielectrons are penetrating probes which carry unaffected information on the hot and dense medium created in ultra-relativistic heavy-ion collisions. The low-mass region of the dielectron spectrum (m_π ⁰ < m_ee < m_ρ) is sensitive to virtual photon production and in-medium modifications of low-mass vector meson spectral functions. These modifications are connected to the restoration of chiral symmetry, which is expected at high temperature. Dielectrons are also sensitive to heavy-flavor production.

In these proceedings, we present the preliminary results of dielectron measurements in pp collisions at √s = 7 TeV, in p-Pb collisions at √s_NN = 5.02 TeV and in central (0-10%) Pb-Pb collisions at √s_NN = 2.76 TeV with the ALICE experiment at the LHC. The expected scenario and perspectives for the dielectron measurement after the ALICE upgrade are also discussed.
