The $\rm J/\psi$ nuclear modification factor as a function of $p_{\rm T}$ at backward (top), mid (center) and forward (bottom) rapidities Statistical uncertainties are represented by vertical error bars, while open boxes correspond to uncorrelated uncertainties and the shaded areas to uncertaintiespartially correlated in $p_{\rm T}$. The boxes around $R_{\rm pPb}=1$ show the size of the correlated uncertainties The horizontal bars correspond to the widths of the $p_{\rm T}$ bins. Results from various models are also shown, including a pure shadowing calculation based on the EPS09 parameterization, a CGC-inspired model, and the results of the coherent energy loss calculation, with or without the inclusion of an EPS09 shadowing contribution.
