Abstract

The reactions pp –> p(f)(X-0)p(s), where X-0 is observed decaying to pi(0)pi(0)pi(0)pi(0), pi(+)pi(-)pi(+)pi(-) and pi(+)pi(-)pi(0)pi(0), have been studied at 450 GeV/c. There is evidence for an a(2)(1320)pi decay mode of the eta(2)(1645) and eta(2)(1870) in the pi(+)pi(-)pi(0)pi(0) and pi(+)pi(-)pi(+)pi(-) find states. The f(2)(1950) is consistent with being a single resonance with a dominant f(2)(1270)pi pi decay mode. The f(0)(1370) is found to decay dominantly to rho rho while the f(0)(1500) is found to decay to rho rho and sigma sigma. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
