The Λ(1405)1/2- resonance is discussed and a fit of the Bonn-Gatchina (BnGa) partial-wave- analysis group is presented to data relevant for this resonance. In the Σπ - NK coupled channel system, no Σ pole and only one Λ pole in the mass range from the Σπ threshold to 1500 MeV is required to get a good description of the data.

Channel Formalism

From dispersion relation approach, a formalism that describes final state interaction among three particles in a coupled-channel system is presented. Different representations of coupled-channel three-body formalism for spinless particles in both initial and final states are derived.

AbstractWe demonstrate the construction of a density of states from the S-matrix describing a coupled-channel (S-wave $$\pi \pi , K {\bar{K}}$$ π π , K K ¯ ) system, and examine the influences from various structures of particle dynamics: poles, roots, and Riemann sheets.
