Description

Recent experiments of the ANKE collaboration concerning the phi meson production in pA-reactions p (2.83 GeV) + C, Cu, Ag and Au are appropriate for the absorptive phi-N interaction within the trancparency ratio. With the aim of analyzing the amount of phi absorption we applied our well confirmed transport model of Boltzmann-Ühling-Uhlenbeck (BUU) type on this scenario. The results seem to point to an absorption cross section of 18 \pm 3 mb only when accounting for secundary phi production processes as well as isospin asymmetry and ANKE acceptance conditions.
