    "abstract": "We investigate the origin of subthreshold $K^+$ production in heavy ion\ncollisions at intermediate energies. In particular we study the influence of\nthe pion induced $K^+$ creation processes. We find that this channel shows a\nstrong dependence on the size of the system, i.e., the number of participating\nnucleons as well as on the incident energy of the reaction. In an energy region\nbetween 1--2 GeV/nucleon the pion induced processes essentially contribute to\nthe total yield and can even become dominant in reactions with a large number\nof participating nucleons. Thus we are able to reproduce recent measurements of\nthe KaoS Collaboration for 1 GeV/nucleon Au on Au reactions adopting a\nrealistic momentum dependent nuclear mean field.",
