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 s
tudied at 450 GeV/c. There is evidence for an a(2)(1320)pi decay mode of th
e eta(2)(1645) and eta(2)(1870) in the pi(+)pi(-)pi(0)pi(0) and pi(+)pi(-)p
i(+)pi(-) find states. The f(2)(1950) is consistent with being a single res
onance 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 rh
o rho and sigma sigma. (C) 2000 Published by Elsevier Science B.V. All righ
