Abstract K −-meson production in proton-nucleus interactions at projectile energies up to 15 GeV is studied. As a first step the available data onK −-meson production inpp interactions are compared with different parametrizations and results of model calculations. Because of considerable uncertainties in the current descriptions of the energy dependence of the elementaryK − cross section a new parametrization is suggested. Experimental data on K− production in pA collisions are analyzed in the framework of the Rossendorf-Collision and folding models. Satisfactory descriptions of the momentum spectra at forward angles are achieved. From an analysis of theA dependence it can be concluded thatK − mesons are well suited to investigate final-state interactions for particles interacting strongly with the residual nucleus. Furthermore, we propose experimental studies onK − production close to threshold. Such measurements are particularly sensitive to contributions from secondary processes or from multi-nucleon interactions.
