Strangeness Flow in Collisions at Measured with HADES

Abstract

We present preliminary results on anisotropic flow of particles with strangeness content in Au Au collisions at measured with HADES. The strange particle flow in heavy-ion collisions is a good probe for the nuclear equation-of-state. Kaon flow was rarely measured at such low centre-of-mass energies, due to the sub-threshold production of strangeness. Thanks to the large statistics of 2.6 billion most central collisions, this study is now possible. The obtained flow parameters (differential measurement of directed and elliptic flow w.r.t. centre-of-mass rapidity and transverse momentum) are compared with previously published world data as well as with flow of non-strange particles.
