...of = 0:04 was sucient to reproduce the early EMC data. However, we will show that the ideas of shifting the value of xAbased on binding energy or separation energy considerations violates rigorous (Collins, 2013) baryon and momentum sum rules, and therefore cannot be a viable explanation of the EMC eect. Consider a nuclear model in which nucleons are the only degrees of freedom. There will be a conserved bar...

...On the other hand, if one first regularizes the light-cone singularities of TMD FFs, and afterwards performs the kT integration one no longer has simple relations of the type (41)-(43) — see for instance [88, 12]....

...When taking into account higher-order QCD effects this parton model interpretation of FFs gets distorted [12]....

...Moreover, we have suppressed the dependence of ∆ on a renormalization scale μ, which is caused by the renormalization of the two quark field operators and a divergence arising from the integration upon the transverse quark momentum [12]....
