"Figure 3" of "Probing the gluonic structure of the deuteron with $J/\psi$ photoproduction in d+Au ultra-peripheral collisions"

Upper - differential cross section as a function of $p^{2}_{T, J/\psi}$ of \jpsi photoproduction in UPCs at $\sqrt{s_{_{\rm NN}}}=200\rm~GeV$. Data for the total diffractive process are shown with solid markers, while data with neutron tagging in the deuteron-going ZDC are shown with open markers. Theoretical predictions based on the saturation model (Color Glass Condensate)[Phys.Rev.C 101 (2020) 1, 015203] and the gluon shadowing model (LTA) [V. Guzey, M. Strikman, E. Kryshen, M. Zhalov] are compared with data, shown as solid lines. Statistical uncertainty is represented by the error bars, and the systematic uncertainty is denoted by the shaded box. For the lower, ratios of total data and models are presented as a function of $-t \approx p^{2}_{T, J/\psi}$. Color bands are statistical uncertainty based on the data only, while systematic uncertainty is indicated by the gray box.
