We have developed an analytic continuation method for extracting parameters of nucleon resonances within a Hamiltonian formulation of meson-nucleon reactions. T
The six- and four-quark systems are studied in the framework of constituent quark models. It is emphasized that the color confinement used in multiquark system
We report our recent work on a hadronic molecule state of the K(K)N system with I=1/2 and J~P=1/2~+. We assume that the A(1405) resonance and the scalar mesons,
We present recent investigations on the vector and axial-vector transitions of the baryon antide-cuplet within the framework of the self-consistent SU(3) chiral
The spectrum and properties of the excited states of the nucleon are still poorly established despite decades of study. These proceedings describe new measureme
