Production and Flow of Strange Particles in FOPI — •Markus Merschmeyer — Physikalisches Institut der Universität Heidelberg, Philosophenweg 12, 69120 Heidelberg
Heavy-ion collisions at relativistic energies offer
the possibility to study states of hot and compressed
nuclear matter.
Hadron properties are expected to change within this
environment. Prodution yield and phase space distributions
of strange particles are two independent tools to probe
those in-medium effects.
A high-statistics data sample was taken for Ni+Ni at
1.93 AGeV. The 4π production yields and the flow
behaviour of reconstructed K0 and Λ have
been studied. Detailed comparisons to microscopic model
calculations have been performed.
The talk will present results of the analysis of neutral
strange particles. Furthermore, the status of the search
for double-strange baryons and kaonic clusters is
reported.
