Description
A global NPDF analysis of the combined charged-lepton DIS, DY and
neutrino DIS data finds a tension between the nuclear correction
factors in nA DIS and ℓA DIS. We explore possible sources of this
tension by comparing the input PDFs used by different nuclear global
fitting groups, and also compute ratios of experimental observables
which (largely) minimize any theoretical bias. We also show
comparisons with recent nPDF determinations. This work helps to
isolate the sources of possible tensions in the extracted nuclear
corrections.
