$J / ψ$ photoproduction near threshold and signals for the hidden charm pentaquarks

Ming-Xiao Duan, Chang Gong, Lin Qiu +1

We study the $J / ψ$ photoproduction $γ p \to J / ψ p$ near threshold to investigate the role played by the open charm channels and possible signals from the hidden charm $P_{c}$ pentaquark…

Coupled-channel description of charmed heavy hadronic molecules within the meson-exchange model and its implication

Lin Qiu, Chang Gong, Qiang Zhao

Motivated by the first observation of the double-charm tetraquark $T_{cc}^{+} (3875)$ by the LHCb Collaboration, we investigate the nature of $T_{cc}^{+}$ as an isoscalar $D D^{*}$ hadroni…
