Title: Frisco3 - A three-fluid model with continuous freeze-out for intermediate energy heavy-ion collisions
Abstract: Frisco3 is a novel 3-fluid hydrodynamical simulation model of relativistic heavy-ion reactions with a continuous transition from the fluid phase to the regime of free streaming hadrons. The time evolution of the reaction is consistently described in terms of three coupled ideal fluids, resembling the two nuclei and the fireball respectively, and a drain term, which is determined by the local thermal emissivity and the survival probability of produced hadrons given by their momentum differential, temperature and density dependent scattering rate in the medium. The drain from the fluid phase is irrecoverably transferred into the observable hadronic final state. Here, first benchmarking results on hadron multiplicities, rapidity and transverse momentum spectra and freeze-out properties related to the phase diagram are presented for Au+Au collisions ranging from 3 GeV to 20 GeV center of mass energy.
