Nonexistence of hidden-charm pentaquarks in $J / I ¨ $ photoproduction

Samson Clymton, Sang-Ho Kim, Hyun-Chul Kim

We investigate $J / I ¨ $ photoproduction off the proton, $I^^{3} p \to J / I ¨ p$ , to elucidate the nonexistence of hidden-charm pentaquark signals reported by the GlueX and CLAS12 experiments…

Probing hidden-charm pentaquarks from the $I ¨ N \to J / I ¨ N$ reaction

Samson Clymton, Sun-Young Ryu, Jung-Keun Ahn +1

We investigate the dynamical generation of hidden-charm pentaquark resonances in the $I ¨ N \to J / I ¨ N$ reaction utilizing an off-shell coupled-channel formalism. Motivated by the abs…

Dynamical generation of charmonium-like tetraquarks in an off-shell coupled-channel formalism

Hee-Jin Kim, Hyun-Chul Kim

We investigate the dynamical generation of charmonium-like ( $I = 0$ ) with spin-parity $J^{P C} = 0^{++}, 1^{++}, 2^{++}$ , and $3^{--}$ in the mass range of $3.6$ to $4.3$ GeV. We employ…

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 $D ˉ_{s} I^c ◯_{c}$ ,…

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…
