Query: The nature of the Lambda(1405) resonance in chiral dynamics   The Lambda(1405) baryon resonance plays an outstanding role in various
aspects in hadron and nuclear physics. It has been considered that the
Lambda(1405) resonance is generated by the attractive interaction of the
antikaon and the nucleon, as a quasi-bound state below the threshold decaying
into the pi Sigma channel. Thus, the structure of Lambda(1405) is closely
related to the Kbar N interaction which is the fundamental ingredient to study
few-body systems with antikaon. In this paper, after reviewing the basic
properties of the Lambda(1405) resonance, we introduce the dynamical
coupled-channel model which respects chiral symmetry of QCD and the unitarity
of the scattering amplitude. We show that the structure of the Lambda(1405)
resonance is dominated by the meson-baryon molecule component and is described
as a superposition of two independent states. The meson-baryon nature of
Lambda(1405) leads to various hadronic molecule states in few-body systems with
strangeness which are hadron composite systems driven by the hadronic
interactions. We summarize the recent progress in the investigation of the
Lambda(1405) structure and future perspective of the physics of the
Lambda(1405) resonance.
