D. Barberis et al., A STUDY OF THE K(K)OVER-BAR-PI CHANNEL PRODUCED CENTRALLY IN PP INTERACTIONS AT 450 GEV C/, Physics letters. Section B, 413(1-2), 1997, pp. 225-231
Results are presented of an analysis of the reactions pp --> p(f)((KsK
)-K-0 (+/-) pi(-/+))p(s) and pp --> p(f)((KsKs0)-K-0 pi(0))p(s) at 450
GeV/c. Clear f(1)(1285) and f(1)(1420) signals are seen and a spin pa
rity analysis shows that both have I(G)J(PC) = 0(+) 1(++). The f(1)(12
85) decays to a(0)(980)pi and the f(1)(1420) decays to K(K) over bar
Both states have a similar dependence as a function of dP(T) consisten
t with what has been observed for other q (q) over bar states. Evidenc
e is also presented for a K(K) over bar decay mode of the eta(2)(1620
). (C) 1997 Elsevier Science B.V.
