摘要：
In this study, the changes in the dilepton production cross section have been investigated by adding quark distribution functions of bound pions beside the quark distribution functions of bound nucleons in the framework of the Shell and Fermi gas models. Similar extracted results from two aforementioned models showed that by considering the pionic contribution the consistency between the theoretical results and the experimental data could be improved about 3-8%.
