The EMC effect

A review is presented of data and theoretical interpretations of the nuclear dependence of quark and antiquark distributions as observed in the deep inelastic scattering of neutrinos and charged leptons from nuclei. After a summary of the experimental situation and a survey of the broad spectrum of proposed explanations, I concentrate on the Q2‐rescaling approach and on interpratations, I concentrate on the Q2‐rescaling approach and on interpretations in terms of conventional nuclear physics. The review concludes with a list of desirable future experiments.
