Nuclear modifications to collinear parton distribution functions are conventionally quantified by the ratios $ r^{\textrm{A}}_i(x,Q^2) = f^\textrm{A,proton}_i(x,Q^2) / f^\textrm{proton}_i(x,Q^2) $. For a given nucleus $A$, these ratios…

It has been argued recently that the so-called nuclear modification factor ($R_{AA}$) is an observable useful for identifying the quark-gluon plasma. We discuss the effect of Fermi motion in nuclei on $R_{AA}$ at CERN SPS and BNL RHIC…
