Abstract
Recent results obtained by the COSY-11 collaboration concerning the product ion of eta and eta ' mesons in the pp --> ppMeson reaction are presented. A comparison of the production amplitude for the pi (0), eta and eta ' meson s at the same phase space volume allows to conclude that the protonl-eta ' interaction is in the order of, or smaller than, the proton-pi (0) one. A t otal cross section determined in a preliminary analysis of the data of elem entary kaon and antikaon production via the pp --> pp K K+ (-) reaction mea sured at excess of energy of Q = 17 MeV is reported.
