Abstract A study of the f 1 (1285) and f 1 (1420) produced in central pp interactions has been performed. For the first time in a single experiment the branching fractions of both mesons in all major decay modes have been determined. Both the f 1 (1285) and f 1 (1420) are consistent with being produced by double Pomeron exchange.A study of the f1(1285) and f1(1420) produced in central pp interactions has been performed.

A partial wave analysis of the centrally produced pi+pi- channel has been performed in pp collisions using an incident beam momentum of 450 GeV/c. An unambiguous physical solution has been found. Evidence is found for the f0(980), f0(1300), f0(1500) and fJ(1710) with J = 0 in the the S-wave. The rho(770) is observed dominantly in the P0-wave and the f2(1270) is observed dominantly in the D0-wave. In addition, there is evidence for a broad enhancement in the D-wave below 1 GeV.A partial wave analysis of the centrally produced pi+pi- channel has been performed in pp collisions using an incident beam momentum of 450 GeV/c.

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.A study has been made of pseudoscalar mesons produced centrally in pp interactions.
