Abstract
A partial wave analysis of (p) over barp --> eta eta pi (0) data from the C rystal Barrel experiment is made in terms of s-channel resonances. The deca y channels a(0)(980)eta, f(0)(1770)pi and f(0)(2105)pi provide evidence for two I = 1, J(PC) = 0(-+) resonances. The first has mass M = 2360 +/- 25 Me V and width Gamma = 300(-50)(+100) MeV, and the second M = 2070 +/- 35 MeV, Gamma = 310(-50)(+100) MeV. There is also evidence for a J(PC) = 2(-+) sta te with M = 2005 +/- 15 MeV and Gamma = 200 +/- 40 MeV, decaying strongly t o a(0)(980)pi. (C) 2001 Published by Elsevier Science B.V.
