Relativistic view on the nuclear effects in the deep inelastic scattering on deuteron

We analyze nuclear effects in the deep inelastic scattering on deuteron in the framework of the covariant approach. It is shown that this approach gives us the way to investigate the role of relativistic effects in the deep inelastic scattering (DIS) on deuteron, such as the relativistic kinematics and the off-mass-shell behavior of the Compton amplitude of nucleon in the consistent manner. We have obtained that taking into account of the nucleon amplitude off-mass-shell behavior gives us an analog of the interaction corrections in nonrelativistic models.
