The reaction pp → p(f)(ωω)p(s) has been studied at 450 GeV/c and a spin analysis of the ωω channel has been performed for the first time in central production. Evidence is found for the f2(1910) in the J(PC) = 2++ wave with spin projection J(Z) = 2. This is the only state observed in central production with spin projection J(Z) = 2. Its dP(T) and φ dependencies are similar to those observed for other glueball candidates. In addition, evidence is found for a state with J(PC) = 4++ consistent with the f4(2300). The f0(2000), previously observed in the pp final state, is confirmed. (C) 2000 Elsevier Science B.V.
