Anisotropic flow and the reaction plane reconstruction with the CBM experiment

The Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) will study heavy-ion collisions at beam energies 2-35 AGeV. The Projectile Spectator Detector (PSD) of the CBM is a compensating hadron calorimeter, which will measure projectile spectator nucleons and fragments with the aim to determine reaction centrality and reaction plane. Results of particles flow simulation and the reaction plane reconstruction performance with the PSD detector are presented. Directed flow and reaction plane resolution are simulated for Au+Au collisions using four heavy-ion collision event generators: UrQMD, DCM-QGSM, LA-QGSM and HSD. Simulations are performed for the range of beam energies between 2 and 30 AGeV, which covers the expected beam energies of SIS100 and SIS300 accelerator rings at FAIR. Results are compared with the experimental data from AGS E877, E895 and STAR.
