Disentangling Explanations of Deep-Inelastic Lepton-Nucleus Scattering by Lepton-Pair Production

Abstract

Deep-inelastic lepton-nucleus scattering has shown that the momentum distribution of quarks in a nucleon is modified by the nuclear environment. Several different explanations have been proposed. These can be distinguished by proton-nucleus scattering experiments which measure the production of lepton pairs in certain kinematic regions.
