What We Know About the Lambda(1405)

Abstract

The current status of the Lambda(1405) resonance in the Kbar N scattering is summarized. It is shown that the precise experimental data and the theoretical developments in chiral SU(3) dynamics enable us to quantitatively understand the physics around the Kbar N threshold. We present the recent theoretical predictions of the pi Sigma spectrum and the investigations of the internal structure of the Lambda(1405).
