Abstract

One of the fundamental objectives of experiments with ultrarelativistic heavy ions is to explore strongly interacting matter at high baryon density and high temperature. In this investigation we apply a hadronic transport approach to study in particular the information that can be obtained by analyzing baryonic and mesonic resonances. The decay products of these resonances carry information on the resonances properties at the space-time point of their decay. We especially investigate the percentage of reconstructable resonances as a function of baryon density for heavy-ion collisions in the energy range between Elab=30 A GeV and s=200 A GeV, the energy domain between the future GSI Facility for Antiproton and Ion Research and the present BNL Relativistic Heavy Ion Collider. It is shown that a transverse-momentum-dependent analysis of resonances might be beneficial for investigating the high-baryon-density phase of heavy-ion collisions.
