It is shown that original momentum distributions and abundance of resonances formed during the process of heavy-ion collisions may differ significantly from their measured spectra and yields. The reconstruction probability of resonances decaying inside the fireball can be strongly suppressed because of interactions of their hadronic decay products in the fireball medium. We investigate the dependence of the degree of suppression on the fireball size, dynamics and the resonance decay width in the medium. Quantitative results are presented for lead-lead collisions at 158 GeV SPS beam energy. Public work category ADC No. of Archival Copy 26394 Catal.org.
