Determination of phi-meson nuclear modification factors in the proton-lead nucleous interactions in the ALICE experiment at the LHC

Hadronic resonances are among the most interesting probes of the hot and dense matter created in Pb + Pb collisions. Due to their short lifetime, they are sensitive to the anticipated chiral symmetry restoration as well as to suppression and regeneration due to hadronic interactions in the final state. At intermediate and high transverse momenta (pT) resonances which cover the range of masses between the light pions and heavier protons contribute in systematic study of the baryon puzzle and parton energy loss in the dense medium. Studies in p + Pb collisions are important for the interpretation of heavy ion results as they allow to decouple and understand the cold nuclear matter effects from final state effects. The systematic study of the phi (1020) meson production at mid-rapidity in p + Pb collisions at LHC energies has been performed. In this article the most recent results of these studies including pT spectra and nuclear modification factor distributions in p + Pb collisions at an energy of √(s_NN) = 5.02 TeV are presented.
