Partial wave analysis of (p)over-barp annihilation channels in flight withI=1, C =+1

A combined analysis is reported of 3 pi (0), pi (0), pi (0)eta and pi (0)et a ' data in the mass range 1960 to 2410 MeV. This analysis is made consiste nt also with eta eta pi (0) data, reported separately. The analysis require s s-channel resonances with a spectrum close to that published earlier for C = +1 states with I = 0; masses for I = 1 states are lower on average by 2 0 MeV. Two alternative solutions are found, differing only for J(P) = 2(+) and 4(+) states by small amounts in masses and widths. Both 3 pi (0) and et a pi (0) data prefer one of these two solutions. For this preferred solutio n, observed states have J(PC), masses and widths (M, Gamma) in MeV as follo ws: 4(-+): 2250 +/- 15, 215 +/- 25), 4(++): (2255 +/- 40, 330(-50)(+110)) a nd (2005(-45)(+25), 180 +/- 30), 3(++): (2275 +/- 35, 350(-50)(+100)) and ( 2031 +/- 12, 150 +/- 18), 2(-+): (2245 +/- 60, 320(-40)(+100)) and (2005 +/ - 15, 200 +/- 40), 2(++): (2255 +/- 20, 230 +/- 15), (2175 +/- 40, 310(-45) (+90)) and (2030 +/- 20, 205 +/- 30), and 1(++): (2270(-40)(+55), 305(-35)( +70)). There are indications of further 2(-+), 2(++) and 1(++) contribution s just below the available mass range, and also a 0(++) state at similar to 2025 MeV. (C) 2001 Elsevier Science B.V.
