Hadronic few-body systems in chiral dynamics, -- Few-body systems in hadron physics --
Hadronic composite states are introduced as few-body systems in hadron physics. The Λ(1405) resonance is a good example of the hadronic few-body systems. It has turned out that Λ(1405) can be described by hadronic dynamics in a modern technology which incorporates coupled channel unitarity framework and chiral dynamics. The idea of the hadronic KˉN composite state of Λ(1405)

is extended to kaonic few-body states. It is concluded that, due to the fact that
K
and
N
have similar interaction nature in s-wave

couplings, there are few-body quasibound states with kaons systematically just below the break-up thresholds, like
