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…

Rescattering effects in near-threshold $J / ψ$ photoproduction

S. Sakinah, Sang-Ho Kim, H. M. Choi

We investigate near-threshold $J / ψ$ photoproduction off the nucleon, focusing on hadronic rescattering effects induced by open-charm meson-baryon intermediate states. Beyond the co…

Production of $K^{} Σ$ and $D^{} Σ_{c}$ in pion-induced reactions off the nucleon

Sang-Ho Kim

We investigate the mechanisms of strangeness production in the $π^{-} p \to K^{* 0} Σ^{0}$ and $π^{-} p \to K^{*+} Σ^{-}$ reactions within a hybrid Regge framework in which effective Lagran…
