Abstract

Abstract The pp → KK and π + π − annihilation reactions are consistently investigated in a model with both the baryon-exchange diagrams and the meson pole diagrams. The main feature, the backward enhancement, of the observed differential cross sections for pp → KK and π + π − between 360 to 1550 MeV/ c is well understood in this model while the analyzing powers are reasonably reproduced. Specific to the strangeness aspect in pp → KK is that the meson pole diagrams are more important than the baryon-exchange diagrams. Among the meson pole diagrams the tensor meson f 2 dominates the back angle behaviour of differential cross sections.
