    "abstract": "We study systematically the production of strangeness in nuclear reactions\nfrom SIS to SPS energies within the covariant hadronic transport approach HSD.\nWhereas the proton and pion rapidity distributions as well as pion transverse\nmomentum spectra are well described in the hadronic transport model from 2-200\nAGeV, the $K^+$ and $K^-$ spectra are noticeably underestimated at AGS energies\nwhile the $K^+$ spectra match well at SIS and SPS energies with the\nexperimental data. We conclude that the failure of the hadronic model at AGS\nenergies points towards a nonhadronic phase during the collision of heavy\nsystems around 10 AGeV.",
