We investigate the possible difference in momentum distributions of phi mesons measured via their leptonic (mu (+),mu (-)) and hadronic (K+ K-) decays. Rescattering of secondary kaons in the dense hadron gas together with the influence of in-medium kaon potential can lead to a relative decrease of the phi yield observed in the hadronic channel. We analyze how the in-medium modifications of meson properties affect apparent, reconstructed momentum distributions of phi mesons. Quantitative results are presented for central Pb+Pb collisions at E-beam = 158 GeV/nucleon. Public work category ADC No. of Archival Copy 26396 Catal.org.
