The Single Particle Sum Rules in the Deep-Inelastic Region

Abstract

We have modelled parton distribution in nuclei using a suitably modified nuclear Fermi motion. The modifications concern the nucleon rest energy which changes the Björken x in nuclear medium. We also introduce final state interactions between the scattered nucleon and the rest of the nucleus. The energy-momentum sum rule is saturated. Good agreement with experimental data of the EMC effect for $x>0.15$ and nuclear lepton pair production data has been obtained.
