The partonic structure of the pion at large-x

Unlike the proton, whose parton distributions have been extracted using abundant data, the pion has been relatively ignored. The pion, nevertheless, is a crucial part of the current understanding of the nucleon’s parton distributions and of the binding of the nucleon into a nucleus. The pion’s structure becomes more intriguing when its dual roles as a light quark‐antiquark system and as QCD’s Goldstone boson are considered. One source of data on the pion’s structure is pion‐induced Drell‐Yan scattering. Two recent re‐analyses of such data are discussed here.
