Description
Nucleon structure functions, as measured in lepton-nucleon scattering, have historically provided a critical observable in the study of partonic dynamics within the nucleon. However, at very large parton momenta it is experimentally and theoretically challenging to extract parton distributions due to the onset of non-perturbative contributions. New results will be presented from experiment E12-10-002 carried out in Jefferson Lab Experimental Hall C on the deuteron to proton cross–section ratio at large Bjorken-x that significantly improves on the precision of existing data, as well as a first look at the expected impact on quark distributions extracted from global parton distribution function fits.
