Flow at SIS using the Scalar product method — •Mathilde Himmelreich for the HADES collaboration — Goethe-Universität Frankfurt

Collective flow phenomena are a sensitive probe of hot and dense matter created in relativistic heavy-ion collisions. The analysis of this phenomena depends on an accurate calculation of the reaction plane. In this contribution we compare two different procedures with focus on achievable resolution for the reconstruction of the reaction plane in Au-Au collisions at 1.23 AGeV recorded with HADES: event plane and scalar product method. The latter permits an event-by-event correction of the event plane and the possibility to examine possible dependencies of its resolution. We show a comparative study between the two approaches to evaluate the influence of systematic effects as a function of centrality, efficiency and rapidity. For this purpose we analysed the directed and elliptic flow (v₁ and v₂) of protons and charged pions using simulations and HADES data taken in April 2012.
