Abstract

We will study the contribution of Pauli Blocking effects to the flavor structure of the Proton sea. This is an important issue as it tell us about the nonperturbative regime of quark physics. Moreover, there are contradictory approaches to this problem in the literature, and our aim is to find the final, most consistent, answer to the problem in question. Finally, we will interact with the local staff of the laboratory, as the Jefferson Lab is, currently, the most important center in the world, which studies the quark-hadron transition region. (AU)
