Coherent Photoproduction of Low- Charmonium in Peripheral Heavy Ion Collisions within the Color Dipole Model

Figure 1

The very low- yield in relativistic heavy ion collisions. The dash line (red) is for the GBW model, the dash-dot line (wine) is for the BGBK model, and the dash-dot-dot line (blue) is for the CGC model. The data points are from the STAR Collaboration [32].
