Abstract

A study has been made of pseudoscalar mesons produced centrally in pp interactions. The results show that the eta and eta’ appear to have a similar production mechanism which differs from that of the pi(0). The production properties of the eta and eta’ are not consistent with what is expected from double Porneron exchange. In addition the production mechanism for the eta and eta’ is such that the production cross section are greatest when the azimuthal angle between the p(T) vectors of the two protons is 90 degrees.
