Multi-strange and charmed hadrons: A novel probe for the QCD equation of state at high baryon densities

Nuclear experiments near and below the threshold of hyperon production have shown that the production of Kaons is a sensitive probe for the dense QCD equation of state. At beam energies up to 1.5AGeV, strangeness production can probe the…
