SUMMARY:From C to Proton Sea: Bjorken-x Dependence of the Parton Distribut
 ion Functions - Huey-Wen Lin (Michigan State University)

DESCRIPTION:Studying the structure of nucleons is not only important to un
 derstanding the strong interactions of quarks and gluons\, but also to imp
 roving the precision of new-physics searches. Since a broad class of exper
 iments\, including the LHC and dark-matter detection\, require Standard-Mo
 del backgrounds with parton distribution functions (PDFs) as inputs for di
 sentangling SM contributions from potential new physics. For a long time\,
  lattice calculations of the PDFs (as well as many hadron structures) has 
 been limited to the first few moments. In this talk\, we present a first d
 irect calculation of the Bjorken-x dependence of the PDFs using Large-Mome
 ntum Effective Theory (LaMET). An exploratory study of the antiquark/sea f
 lavor asymmetry of these distributions will be discussed. This breakthroug
 h opens an exciting new frontier calculating more complicated quantities\,
  such as gluon structure and transverse-momentum dependence\, which will c
 omplement existing theoretical programs for the upcoming Electron-Ion Coll
 ider (EIC) or Large Hadron-Electron Collider (LHeC).
