Feasibility studies for the measurement of collective phenomena with multiparticle azimuthal correlations and cumulants in CBM at FAIR — •Ante Bilandzic for the CBM collaboration — Technical University of Munich, TUM School of Natural Sciences, Department of Physics, Garching, Germany

In non-central heavy-ion collisions, the initial volume containing the strongly interacting nuclear matter is anisotropic in the coordinate space, due to the leading-order ellipsoidal geometry of non-central collisions. Multiple interactions within this anisotropic volume cause the anisotropy to be transferred from the coordinate space into the momentum space via the thermalized medium, resulting in the anisotropic flow phenomenon. Anisotropic flow is a sensitive probe of the equation of state and transport properties of produced matter, particularly of its shear viscosity.

In this contribution, the status of feasibility studies for measuring collective anisotropic flow with multiparticle azimuthal correlations and cumulants is presented for data-taking conditions in the CBM experiment at FAIR.

Keywords: collective anisotropic flow; multiparticle azimuthal correlations; cumulants
