"Can the sea quark angular momentum help with understanding the nucleon spin"

Dr. Andi Klein

Los Alamos National Lab

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.
