Preliminary study for dilepton flow analysis with CBM — •Simon Neuhaus for the CBM collaboration — Bergische Universität Wuppertal, Wuppertal, Deutschland

Dileptons enable the study of the early phases of the quark-gluon-plasma formed in heavy-ion collisions, as they escape the medium without QCD interactions. Their particle flow characterized by flow coefficients v_n (n = 1, 2, ...) allows us to probe azimuthal anisotropies of these early phases. While dilepton flow has already been investigated in experiments including HADES, no corresponding studies exist yet for the upcoming CBM experiment.

This talk will present the preliminary study of the reconstruction of the dilepton flow at the upcoming CBM experiment. CBM is a fixed-target heavy-ion experiment currently under construction at FAIR/GSI. Additionally, we evaluate the impact of electron identification purity on the physics case of flow reconstruction. This study is based on simulations of Au-Au collisions generated with SMASH at 8 AGeV collision energy.
