Question: The (1385) hyperon is produced in the reaction K - + p - + + (1385), but is not observed in

The Σ (1385) hyperon is produced in the reaction K^- + p → π^- + Σ⁺ (1385), but is not observed in K⁺ + p→π⁺ + Σ⁺ (1385). Its width is Γ = 50 MeV; its main decay channel is π ⁺ Λ.

(a) Is the decay strong or weak?

(b) What are the strangeness and the isospin of the hyperon?
