The isobar model and the resonance model are applied for the first analysis of the subthreshold K+-meson production in proton-carbon collisions, which was perfomed at GSI at an emission angle of 40 degrees and a bombarding energy of 1.2 GeV. In this study, we focus on the role of the secondary processes πN → K+ Y in normal nuclear matter density. It turns out that the present approach can reproduce very well both the π+- and K+- meson spectra. It is also demonstrated that the different kinds of descriptions for the πN → K+ Λ reactions substantially differentiate the calculated results for the p A → K+ X differential cross sections.
