Description
We use an anti-de Sitter/Quantum Chromodynamics (AdS/QCD) based holographic light-front wavefunction for the $J/\psi$ meson, in conjunction with the Color dipole model cross-section to investigate the cross-sections data for exclusive $J/\psi$ electroproduction. We used the dipole model parameters fitted to the most recent 2015 high precision HERA data on inclusive Deep Inelastic Scattering (DIS). Our results suggest that the holographic meson light-front wavefunction with color dipole model is able to give a successful description for rate of diffractive $J/\psi$ electroproduction for HERA data at small $x$ in a wide range of $Q^2$ for the quark mass $m_c= 1.27 $ GeV. We also computed the rapidity distributions of $J/\psi$ meson in dipole model proton-lead ultraperipheral coliisions(UPC). Our predictions are in good agreement with the experimental data of ALICE.
