Recent developments in antikaon-nucleon dynamics

Abstract

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