Nonexistence of hidden-charm pentaquarks in $J / ψ$ photoproduction

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

We investigate $J / ψ$ photoproduction off the proton, $γ p \to J / ψ p$ , to elucidate the nonexistence of hidden-charm pentaquark signals reported by the GlueX and CLAS12 experiments. W…

Probing hidden-charm pentaquarks from the $π N \to J / ψ N$ reaction

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

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

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…
