Excitation Functions of Stopping Power and Flow in Relativistic Heavy-Ion Collisions
Using a relativistic transport (ART) model, we study the stopping power, the formation of superdense hadronic matter as well as the strength of transverse and radial flow in central Au+Au collisions at beam momentum from 2 to 12 GeV/c per nucleon. We find that complete stopping is achieved in the whole beam momentum range. In particular, the proton rapidity distribution scaled by the beam rapid...
متن کاملExcitation function of nucleon and pion elliptic flow in relativistic heavy-ion collisions
Within a relativistic transport (ART) model for heavy-ion collisions, we show that the recently observed characteristic change from out-of-plane to in-plane elliptic flow of protons in mid-central Au+Au collisions as the incident energy increases is consistent with the calculated results using a stiff nuclear equation of state (K= 380 MeV). We have also studied the elliptical flow of pions and ...
متن کاملKaon dispersion relation and flow in relativistic heavy-ion collisions.
Within the framework of a relativistic transport model (ART) for heavy-ion collisions at AGS energies, we examine the effects of kaon dispersion relation on the transverse flow of kaons and their transverse momentum and azimuthal angle distributions. We find that the transverse flow is the most sensitive observable for studying the kaon dispersion relation in dense medium.
متن کاملPion flow and antiflow in relativistic heavy-ion collisions.
Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies, we study the transverse flow of pions with respect to that of nucleons using two complementary approaches. It is found that in central collisions pions develop a weak flow as a result of the flow of baryon resonances from which they are produced. On the other hand, they have a weak antiflo...
متن کاملdependence of transverse flow in relativistic heavy - ion collisions
The strength of transverse flow is examined as a function of transverse momentum p t using a simple, transversely moving thermal model and a more realistic, relativistic transport model (ART). It is shown that the p t dependence reveals useful information about the collective flow that is complementary to that obtained from the standard in-plane transverse momentum analysis. Interesting feature...
