Charged Kaon and φ Production in Ag+Ag Collisions at 1.58A GeV with HADES — •Marvin Kohls for the HADES collaboration — Goethe-Universität Frankfurt
The investigation of strangeness production and propagation in heavy-ion collisions in the few GeV energy regime is a sensitive tool to study the microscopic structure of nuclear matter at high baryo-chemical potential [1].
For respective studies presented in this talk, a total of 6×109 central Ag(1.58 A GeV)+Ag events recorded with HADES in 2019 have been used.
We focus on results concerning K+, K− and φ(1020).
The multiplicities of strange particles are compared with results obtained from statistical hadronization models.
Special attention will be put on the non-strange φ(1020) meson and the double-strange Ξ− hyperon.
Furthermore, the centrality (⟨ Apart⟩) dependence of strange-hadron multiplicities will be discussed, which was found to follow a universal scaling for the collision system Au(1.23 A GeV)+Au.
This work has been supported by BMBF (05P21RFFC2), GSI, HFHF, the State of Hesse within the Research Cluster ELEMENTS (Project ID 500/10.006) and HGS-HIRe.
