2 Aug 2016 | Abstract: | We present a new event generator based on the three-fluid hydrodynamics
approach for the early stage of the collision, followed by a particlization at
the hydrodynamic decoupling surface to join to a microscopic transport model,
UrQMD, to account for hadronic final state interactions. We present first
results for nuclear collisions of the FAIR/NICA energy scan program (Au+Au
collisions, $sqrt{s_{NN}}=4-11$ GeV). We address the directed flow of protons
and pions as well as the proton rapidity distribution for two model EoS, one
with a first order phase transition the other with a crossover type softening
at high densities. The new simulation program has the unique feature that it
can describe a hadron-to-quark matter transition which proceeds in the baryon
stopping regime that is not accessible to previous simulation programs designed
for higher energies. | Source: | arXiv, 1608.0965 | Services: | Forum | Review | PDF | Favorites |
