Title: The Nucleon Parton Distribution for Finite Density

Abstract

We present the evolution of the nucleon structure function with barion density in the phenomenological model for the parton distribution in nuclei. The sea parton distributions are described by additional virtual pions in hadron in such a way as to reproduce the nuclear lepton pair production data and saturate the energy-momentum sum rule. The influence of Fermi motion changes the nucleon rest energy and consequently the transverse momentum square of partons inside bound nucleons. Finally we estimate in the Sigma model the critical density where the fluctuations of pion field lead to the chiral symmetry restoration.
