Variational calculation of the ppK- system based on chiral SU(3) dynamics
The ppK{sup -} system, as a prototype for possible quasibound K nuclei, is investigated using a variational approach. Several versions of energy-dependent effective KN interactions derived from…

Motivated by the precise measurement of the $1S$ level shift of kaonic hydrogen, we perform accurate three-body calculations for the spectrum of kaonic deuterium using a realistic antikaon-nucleon…
Compositeness of dynamically generated states in a chiral unitary approach
The structure of dynamically generated states in the chiral unitary approach is studied from a viewpoint of their compositeness. We analyze the properties of bound states, virtual states, and…
Generalized weak-binding relations of compositeness in effective field theory
We study the compositeness of near-threshold states to investigate the internal structure of exotic hadron candidates. Within the framework of effective field theory, Weinberg's weak-binding relation…
