Description |
We conduct a study of the interaction of the K ̄ Ξ , ηΩ(s-wave), and K ̄ Ξ(d-wave) channels within a coupled channel unitary approach where the transition potential between the K ̄ Ξ and ηΩ channels is obtained from chiral Lagrangians. The transition potential between K ̄ Ξ , ηΩ, and K ̄ Ξ is taken in terms of free parameters, which together with a cutoff to regularize the meson-baryon loops are fitted to the Ω(2012) data. We find that all data including the recent Belle experiment on Γ(Ω →πK ̄ Ξ) /Γ(Ω →K ̄ Ξ), are compatible with the molecular picture stemming from meson baryon interaction of these channels. |
