Description
pp → ppπ0 and pp → ppη were considered close to threshold. The pion production was found not only to be dominated by IA and rescattering contributions, but also strongly by box-diagrams, resonances and heavy-meson exchanges. New relevant contributions for the IA were found. The role of the offshell behaviour of nucleon-resonance couplings (P11(1440), S11(1535)) and of interference effects for the eta production was investigated. The results opened a large door for microscopic understanding of short range physics. A covariant model for pp → ppη being under construction is going to be finished. (author)
