Antikaon-nucleon dynamics and its application to few-body systems
  We overview the recent progress in the investigation of the antikaon dynamics with single nucleon and with few-body nuclei, based on chiral SU(3) symmetry. We first show how the Lambda(1405) resonance emerges from the coupled-channel Kbar N-pi Sigma interaction. Next, we present the construction of an up-to-date Kbar N interaction in response to the recent measurement of kaonic hydrogen. Finally, we discuss the possibility of the antikaon bound states in nuclei from the perspective of few-body physics.
