| dc.description | A partial wave analysis of PS185 data for pbar-p to Lambda-bar Lambda is presented. A 3S1 cusp is identified in the inverse process Lambda-bar Lambda to pbar-p at threshold using detailed balance. Partial wave amplitudes for pbar-p 3P0, 3F3, 3D3 and 3G3 exhibit a behaviour very similar to resonances observed in Crystal Barrel data. With this identification, the pbar-p to Lambda-bar Lambda data then provide evidence for a new I = 0, J^{PC} = 1^{--} resonance with mass M = 2290 +- 20 MeV, Gamma = 275 +- 35 MeV, coupling to both 3S1 and 3D1. | |
