The time evolutions of Delta, rho and phi resonances are investigated. Special emphasize is put on resonance regeneration after chemical freeze-out. The emission time spectra of experimentally detectable resonances are explored.Proceedings of the Nuclear Physics Winter Meeting 2005 in BormioNuclear Theorytext
