Low mass dilepton production in pp, p-Pb and Pb-Pb collisions measured with ALICE at the LHC

Abstract : The production of low-mass dileptons, including those from ρ, ω and ϕ light vector meson decays, provides key information on the hot and dense state of strongly interacting matter produced in high-energy heavy-ion collisions. In particular, strangeness production can be studied through ϕ meson measurements, while the detailed description of the full dilepton mass spectra down to the kinematic threshold can be used to reveal in-medium modifications of hadron properties and the thermal emission arising from the medium. Measurements in pp and p–A, respectively, provide a reference for the observations in heavy-ion collisions and give insight on soft particle production in cold nuclear matter. Dilepton production is studied with the ALICE apparatus at the LHC both at central (image) and forward (image) rapidity, respectively in the dielectron and dimuon channel. In this contribution, we present recent results on low-mass dimuon production at forward rapidity in Pb–Pb and p–Pb collisions.
