Recent developments in antikaon-nucleon dynamics

Stimulated by various experimental achievements, the study of K¯N dynamics now enters a new phase. The two-body K¯N interaction is largely constrained by recent experimental data, and the nature of the Λ(1405) resonance is being unveiled by several theoretical analyses. These findings provide a basic tool for applications to K¯-nuclear systems. We summarize the current status of the K¯N phenomenology and outline the future direction in this field.
