Mesonic and binding contributions to the EMC effect in a relativistic manybody approach
Abstract
We revise the conventional nuclear effects of Fermi motion, binding and pionic effects in deep inelastic lepton scattering using a relativistic formalism for an interacting Fermi sea and the local density approximation to translate results from nuclear matter to finite nuclei. In addition we also consider effects from ϱmeson renormalization in the nucleus. The use of nucleon Green functions in terms of their spectral functions offers a precise way to account for Fermi motion and binding. On the other hand the use of manybody Feynman diagrams in a relativistic framework allows one to avoid using prescriptions given in the past to introduce relativistic corrections in a nonrelativistic formalism. We show that with realistic nucleon spectral functions and meson nucleus selfenergies one can get a reasonable description of the EMC effect for x > 0.15, outside the shadowing region.
