Abstract
Data are presented on the reaction (p) over bar p --> omega omega pi(0) at rest from the Crystal Barrel detector. These data identify a strong signal due to f(2)(1565) --> omega omega. The relative production from initial (p) over bar p states (3)p(2), P-3(1) and S-1(0) is well determined from omega omega decay angular correlations; P-state annihilation dominates strongly. A combined fit is made with data on (p) over bar p --> 3 pi(0) at rest, wh ere f(2)(1565) --> pi(0)pi(0) is observed. A Flatte formula is fitted to th e f(2)(1565), including the s-dependence of decay widths to ww and pp. The data then determine the K-matrix mass, M = 1598 +/- 11(stat)+/- 9(syst) MeV . The decay width to 2 pi is very small, of order 2% of the total width. (C ) 1999 Elsevier Science B.V. All rights reserved.
