Abstract:
In this paper we present an analisys regarding flow in heavy ion collisions at energies between 2GeV A and 10 GeVA coresponding to SIS100 accelerator in a fix target experiment. To simulate initial interactions we used two codes UrQMD 3.4 and AMPT v1.26t5. For different classes of centrality directed and elliptic flow for several types of particles are discussed. In the evolution of a heavy ion collisions a significant collective flow is a signature of the formation of QGP and one estimated that in CBM experiment the transition point between hadronic phase of the nuclear matter and quarkyonic phase is reached around 2GeVA.
