Two-pole structure of the axial-vector meson: resolving mass discrepancy
Samson Clymton, Hyun-Chul Kim
We investigate isoscalar axial-vector mesons using a coupled-channel formalism. The kernel amplitudes are constructed from meson-exchange diagrams in the - and -channels, whi…

Production mechanism of the hidden charm pentaquark states
Samson Clymton, Hyun-Chul Kim, Terry Mart
We investigate hidden-charm pentaquark states using an off-shell coupled-channel formalism involving heavy meson and singly heavy baryon scattering. Our approach utilizes an effect…

Two-pole structure of the (1235) axial-vector meson
Samson Clymton, Hyun-Chul Kim
We investigate the dynamical generation of the meson in the interaction, using the fully off-mass-shell coupled-channel formalism with the , , , and $K\bar{K…
