A measurement of the branching fractions of the f1(1285) and f1(1420)   produced in central pp interactions at 450 GeV/c
  A study of the f1(1285) and f1(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 f1(1285) and f1(1420) are consistent with being produced by double Pomeron exchange.
