Abstract
The reaction pp --> p(f)(omega omega)p(s) has been studied at 450 CeV/e and a spin analysis of the omega omega channel has been performed for the firs t time in central production. Evidence is found for the f(2)(1910) in the f (2)(1910) in the J(PC) =2(++) wave with spin projection J(Z)= 2. This is th e only state observed in central production with spin projection J(Z)= 2. I ts dP(T) and phi dependencies are similar to those observed for other glueb all candidates. In addition, evidence is found for a state with J(PC) = 4(+) consistent with the f(2)(2300). The f(0)(2000), previously observed in t he rho rho final state, is confirmed. (C) 2000 Elsevier Science B.V. All ri ghts reserved.
