A spin analysis of the 4π channels produced in central pp interactions at 450 GeV/c

The reactions pp ! pf(X 0 )ps ,w here X 0 is observed decaying to 0000 , + + and + 00 , have been studied at 450 GeV/c. There is evidence for an a2(1320) decay mode of the 2(1645) and 2(1870) in the + 00 and + + nal states. The f2(1950) is consistent with being a single resonance with a dominant f2(1270) decay mode. The f0(1370) is found to decay dominantly to while the f0(1500) is found to decay to and .
