Abstract

The effective mass spectrum of pi(0) pairs produced in pp central collisions (pp --> pf pi(0) pi(0)p(s)) at 450 GeV/c, root s = 29 GeV, below 1 GeV differs from that observed in peripheral charge exchange reactions, In particular, there is a large number of events between pi pi-threshold and 1 GeV, that interfere with f(0)(980) destructively. The possible existence of a broad S-wave state is suggested. (C) 1997 Published by Elsevier Science B.V.
