Colloquium: "The Importance of Nuclear Modifications to the Nucleon Structure"

Electron and muon deep inelastic scattering (DIS) experiments off nuclear targets demonstrated significant nuclear effects on 'quark-distributions' (parton distribution functions), at energies and momenta much higher than typical nuclear binding energies, ruling out the naive picture of the nucleus as a system of quasifree nucleons.

A quantitative explanation of the observed effects requires the presence of an in-medium nuclear modification of parton distribution functions, extending beyond the traditional Fermi motion and binding correction.  We discuss applications to several high energy processes, including lepton-nucleus DIS, Drell-Yan production in proton-nucleus collisions, W^+- and Z^0 boson production in p+Pb collisions at the Large Hadron Collider (LHC), and (anti) neutrino interactions with nuclei.
