Collective flow and correlations measurements with HADES in Au+Au collisions at 1.23 AGeV

Abstract

The HADES experiment provides a large acceptance combined with a high mass resolution and therefore makes it possible to study dielectron and hadron production in heavy-ion collisions with unprecedented precision. With the high statistics of seven billion Au+Au collisions at 1.23 AGeV recorded in 2012 the investigation of collective effects and particle correlations is possible with unprecedented accuracy. We present multi-differential data on directed ($v_1$) and elliptic ($v_2$) flow, and the first measurement of triangular flow ($v_3$), of protons and deuterons.
