Abstract
A study has been made of pseudoscalar mesons produced centrally in pp interactions. The results show that the η and η′ appear to have a similar production mechanism which differs from that of the π0. The production properties of the η and η′ are not consistent with what is expected from double Pomeron exchange. In addition the production mechanism for the η and η′ is such that the production cross section are greatest when the azimuthal angle between the pT vectors of the two protons is 90 degrees.
