Περίληψη:
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 first 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 the only state observed in central
production with spin projection J(Z)= 2. Its dP(T) and phi 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 f(2)(2300). The f(0)(2000), previously observed in the rho rho
final state, is confirmed. (C) 2000 Elsevier Science B.V. All rights
