In a bubble chamber experiment on a K^– beam a sample of events of the reaction K^– + p → Λ⁰ + π⁺ + π^– is selected. A resonance is detected both in the Λ⁰π⁺ and Λ⁰π^– mass distributions. In both, the mass of the resonance is M = 1385 MeV and its width Γ = 50 MeV. It is called Σ (1385). 

(a) What are the strangeness, the hypercharge, the isospin and its third component of the resonance Λ⁰π⁺? 

(b) If the study of the angular distributions establishes that the orbital angular momentum of the Λ0π systems is L = 1, what are the possible spin parity values J_P?
