The role of hidden-charm pentaquark resonance $P_c^{+}(4450)$ in $J/\psi$ photoproduction on nuclei near threshold

E. Ya. Paryev, Yu. T. Kiselev

We study the $J/\psi$ photoproduction from nuclei at near-threshold incident photon energies of 5--11 GeV within the nuclear spectral function approach by considering incoherent direc…
