Calculations of K+, K- and phi Production in Near-Threshold Proton-Nucleus Collisions

Abstract

K+, K- and ϕmeson production in proton-nucleus (pA) collisions has been calculated within a BUU transport model. It is shown that the nucleon-hyperon strangeness transfer channel is essential. The role of three-body reactions has been investigated within the medium. The targetmass dependence of $\varphi$ production is predicted to give important information on the in-medium properties of all three mesons.
