Description
Low-mass dielectrons are an important experimental tool to investigate the properties of the hot and dense medium created in ultrarelativistic heavy-ion collisions. Electrons do not interact strongly, therefore they provide information from all stages of the collision. In particular, a possible restoration of chiral symmetry in the hot and dense medium can be probed with dielectron decays of short-lived hadrons such as $\omega$(782) and $\phi$(1020) mesons, where pp collisions are used as medium-free reference. Furthermore, pp collisions are interesting by themselves to investigate particle production at LHC energies.
In this poster, the status of a measurement of $\omega$(782) and $\phi$(1020) meson production in the $e^{+}e^{-}$- decay channel in pp collisions at $\sqrt{s}$ = 7 TeV with ALICE is presented. The results are compared to measurements in hadronic and $\mu^{+}\mu^{-}$- decay channels.
