Triple-strangeness hidden-charm pentaquarks

Samson Clymton, Hyun-Chul Kim, Terry Mart

We investigate the possible existence of triple-strangeness hidden-charm pentaquark states in the off-shell coupled-channel formalism. The open-charm meson-baryon $D ˉ_{s} Ω_{c}$ , $…

Double-strangeness hidden-charm pentaquarks

Samson Clymton, Hyun-Chul Kim, Terry Mart

We investigate the possible existence of double-strangeness hidden-charm pentaquark states, denoted as $P_{c c ˉ ss}$ , within an off-shell coupled-channel formalism. Eleven meson…

Production mechanism of hidden-charm pentaquark states $P_{c c ˉ s}$ with strangeness $S = - 1$

Samson Clymton, Hyun-Chul Kim, Terry Mart

We investigate the hidden-charm pentaquark states with strangeness $S = - 1$ ( $P_{c c ˉ s}$ ) within an off-shell coupled-channel approach based on effective Lagrangians that respect…

Two-pole structure of the $h_{1} (1415)$ 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 $t$ - and $u$ -channels, whi…
