Description

We solve the \bar{K}NN-\pi YN coupled-channels Alt-Grassberger-Sandhas equations and examine how the \Lambda(1405) resonance manifests itself in the \pi\Sigma invariant mass distributions of \bar{K}d->\pi\Sigma N reactions. Two types of models for the two-body meson-baryon interactions are employed: an energy-independent and an energy-dependent version, both derived from the leading order chiral SU(3) Lagrangian but with different off-shell properties in the three-body \bar{K}NN-\pi YN system.
