ω and φ Meson Analysis via the Dielectron Channel in pp at √s= 7 TeV with ALICE — •Mahmut Özdemir — Institut für Kernphysik, Goethe Universität, Frankfurt

Low-mass dielectrons are an important experimental tool to probe 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, dielectron decays of ω(782) and φ(1020) mesons carry important information on their in-medium properties, where pp collisions are used as medium-free reference for the possible modifications of the medium. Furthermore, pp collisions are interesting by themselves to investigate particle production at LHC energy. In this contribution we will present the status of a measurement of ω(782) and φ(1020) meson production in the e⁺e⁻-decay channel in pp collisions at √s = 7 TeV with ALICE.
