Unique Prediction for High-Energy J/\psi Photoproduction: Color   Transparency and Saturation
  Based on the color-dipole picture, we present a successful parameter-free prediction for the recent high-energy $J/\psi$ photoproduction data from the Large Hadron Collider. The experimental data provide empirical evidence for the transition from color transparency to saturation.
