The f2(1565) in pbar-p -> (omega-omega)pizero interactions at rest
Data are presented on the reaction pbar-p -> omega-omega-pizero at rest from the Crystal Barrel detector. These data identify a strong signal due to f2(1565) -> omega-omega. The relative production from initial pbar-p states 3P2, 3P1 and 1S0 is well determined from omega-omega decay angular co...

| description | Data are presented on the reaction pbar-p -> omega-omega-pizero at rest from the Crystal Barrel detector. These data identify a strong signal due to f2(1565) -> omega-omega. The relative production from initial pbar-p states 3P2, 3P1 and 1S0 is well determined from omega-omega decay angular correlations; P-state annihilation dominates strongly. A combined fit is made with data on pbar-p -> 3pizero at rest, where f2(1565) -> pizero-pizero is observed. |

These data identify a strong signal due to f 2 (1565)→ ωω . The relative production from initial p ̄ p states 3 P 2 , 3 P 1 and 1 S 0 is well determined from ωω decay angular correlations; P-state annihilation dominates strongly. A combined fit is made with data on p ̄ p→3π 0 at rest, where f 2 (1565)→ π 0 π 0 is observed. A Flatté formula is fitted to the f 2 (1565), including the s -dependence of decay widths to ωω and ρρ . The data then determine the K-matrix mass, M =1598±11(stat)±9(syst) MeV. The decay width to 2 π is very small, of order 2% of the total width.Data are presented on the reaction pbar-p -> omega-omega-pizero at rest from the Crystal Barrel detector.
