Inclusive and exclusive (i.e. via the f resonance) K- meson production
cross sections have been measured in proton-proton
reactions at Tbeam = 2.85 GeV. The inclusive K- cross section is
about a factor 20 lower than the K+ cross sections at the
same available energy above threshold.
The observed f/w cross section ratio is enhanced by about an order
of magnitude relative to naive predictions based upon the
Okubo-Zweig-Iizuka (OZI) rule.
Differential cross section results are presented which indicate significant contributions from higher partial
waves in the proton-proton entrance channel.
