摘要:

数据呈现在来自Crystal Barrel检测器的静止反应pbar-p -> omega-omega-pizero上。这些数据识别出由于f2(1565)-> omega-omega引起的强信号。从初始pbar-p态3 P2,3 P1和1 S 0的相对产量是很好地确定从ω-ω衰变角相关; P-态湮灭占主导地位。用静止时的pbar-p -> 3 pizero数据进行组合拟合,其中观察到f2(1565)-> pizero-pizero。

英文摘要:

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.
