Kaons in Dense Nuclear Matter at SIS Energies — •Young-Jin Kim — Gesellschaft für Schwerionenforschung (GSI), Darmstadt, Germany
Kaon production in nucleus-nucleus collisions at SIS energies can deliver insights into fundamental questions in nuclear physics which also have astrophysical implications as the equation of state of nuclear matter and in-medium properties of hadrons. We present the K+/K0 ratio, which has been proposed as a sensitive probe to the isospin dependence of the nuclear equation of state (EoS)[1], for 4496Ru(4096Zr) + 4496Ru(4096Zr) collisions at 1.528A GeV measured with the FOPI detector at GSI. In addition, we show results of charged kaon (K±) flow in Ni + Ni collisions at 1.93A GeV as an observable to study of the kaon properties in the nuclear medium.
