<div align="left"><font face="Times New Roman" size="4">Our current understanding of the origin of the nucleon spin is still limited and we are puzzled by the fact that roughly 50% of the spin is not
accounted for. One of the possible explanations for this spin puzzle of the nucleons could come from including contributions from the angular momentum of the sea quarks. I will discuss the current status, introduce the Drell-Yan process to study the sea quark
behavior and will present a detailed description of a planned and approved experiment at Fermilab with a transversely polarized target.</font></div>
