    "abstract": "We analyse the production and propagation of pions and kaons in heavy-ion\nreactions from 0.8 -- 1.8~A$\\cdot$GeV within a coupled channel transport\napproach including the kaon production channels $BB \\to K^+YN, \\pi B\\to K^+Y,\nBB \\to NN K \\bar{K}, \\pi B\\to N K\\bar{K}, K^+B\\to K^+B $ and $\\pi \\pi\\to K\n\\bar{K}$. Assuming the hyperon selfenergy to be 2/3 of the nucleon selfenergy\nwe find that all inclusive experimental $K^+$ spectra at SIS energies can be\nreproduced reasonably well without any selfenergies for the kaons although a\nslightly repulsive kaon potential cannot be excluded by the present data on\nkaon spectra and flow.",
