Hadronic interaction of eta and eta' mesons with protons


We present results of investigations aiming to determine the hadronic interaction of eta and eta' mesons with nucleons. Inferences are based on comparisons of both the differential cross sections and the close-to-threshold excitation functions for the pp->pp eta and pp->pp eta' reactions with predictions based on the assumption that the kinematically availablephase space is homogeneously populated. We discuss the phenomenology of the initial and final state interaction,relevance of the hadronic and quark-gluon degrees of freedom for thereaction dynamics, and explain in detail the experimental techniquesused for the measurement of the meson production in free and quasi-freecollisions of nucleons
