Hadronic resonance production measured by the ALICE detector at LHC energies

Abstract

Hadronic resonances are a valuable tool to study the properties of the medium formed in heavy-ion collisions. In particular, they can provide information on particleformation mechanisms and on the properties of the medium at freeze-out, and furthermore they contribute to the systematic study of energy loss and recombination. Measurements of resonances in pp and in p-Pb collisions provide a necessary baseline for heavy-ion data and help to disentangle initial-state effects from medium-induced effects. In this proceedings the latest ALICE results on hadronic resonance production in pp, p-Pb and Pb-Pb collisions at LHC energies will be presented. In particular, the production of the K*(892)^0 and o/(1020) resonances at mid-rapidity has been studied in different collision systems at LHC energies, reconstructing the resonances via their hadronic decay in a wide momentum range. The resonance transverse momentum spectra, mean transverse momenta, ratio to stable particles and nuclear modification factor will be discussed
