Abstract

The production and decay properties of the f0(1370), f0(1500), f0(2000) and f2(1950) have been studied in central pp interactions at 450 GeV/c. The dP(T), φ and |t| distributions of these resonances are presented. For the J = 0 states, the f0(1370) and f0(2000) have similar dP(T) and φ dependences. These are different to the dP(T) and φ dependences of the f0(980), f0(1500) and f0(1710). For the J = 2 states the f2(1950) has different dependences to the f2/(1270) and f2/'(1520). This shows that the dP(t) and φ dependences are not just J phenomena. (C) 2000 Published by Elsevier Science B.V.
