Abstract
The reactions pp→pf(X0)ps, where X0 is observed decaying to ηη′ and η′η′, have been studied at 450 GeV/c. This is the first time that these channels have been observed in central production and only the second time that the η′η′ channel has been observed in any production mechanism. In the ηη′ channel there is evidence for the f0(1500) and a peak at 1.95 GeV. The η′η′ channel shows a peak at threshold which is compatible with having JPC=2++ and spin projection JZ=0.
