Abstract
The reaction pp --> P-f(pi(+) pi(-)pi(+)pi(-))p(s) has been studied at 450 GeV/c in an experiment designed to search for gluonic states. A s pin analysis has been performed and the dP(T) filter applied. In addit ion to the well known f(1)(1285) there is evidence for two J(PC) = 2(- +) states called the eta(2)(1620) and eta(2)(1875) and a broad scalar called the f(0)(2000). The production of these states as a function of the dP, kinematical filter shows the behaviour expected for q (q) ove r bar states. In contrast, there is evidence for two states at 1.45 Ge V and at 1.9 GeV which do not show the behaviour observed for q (q) ov er bar states. (C) 1997 Elsevier Science B.V.
