The nature of the Λ (1405) resonance in chiral dynamics

T Hyodo, D Jido - Progress in Particle and Nuclear Physics, 2012 - Elsevier
The Λ (1405) baryon resonance plays an outstanding role in various aspects in hadron and
nuclear physics. It has been considered that the Λ (1405) resonance is generated by the …
