Abstract
Within the frame of an hermitian coupled-channels model we provide a natural explanation for the main properties of p p → Λ \\ ̄ gL experimental data. In particular, the nearthreshold structure is shown to be produced by a narrow Λ \\ ̄ gL subthreshold state of quasinuclear nature. This resonance, produced in the 3SD 1 partial wave, has quantum numbers J PC = 1 −−. The reason for the smallness of its width (few MeV) is explainend. Some experimental possibilities to find this resonance are proposed.
