Abstract
Hadronic resonances measured experimentally by invariant mass reconstruction in relativistic heavy-ion collisions contain contributions from different production channels and/or stages, i.e., leftovers of primordial hadronization, regenerations in hadronic rescatterings and those decayed from heavier resonances. We use a UrQMD model to systematically calculate the proportions of these different channels in final observation of resonances K*(892), Σ*(1385), ϕ(1020), Ξ*(1530) and Λ(1520) and investigate the time evolution of these resonance productions in AA collisions at [Formula: see text], 62.4 and 200 GeV. We study the yields, transverse momentum spectra and elliptic flows of these resonances and discuss the survival information of the primordial hadronization in final observations.
