The role of three-body collisions in phi-meson production processes near threshold
H.W. Barz🇩🇪 · B. Kampfer🇩🇪
Abstract
The amplitude of subthreshold phi-meson production is calculated using dominant tree-level diagrams for three-body collisions. It is shown that the production can overwhelmingly be described by two-step processes. The effect of the genuine three-body contribution (i.e. the contribution which cannot be factorized) is discussed. The production rate of phi-mesons is presented for proton induced reactions on carbon.
