Hall C at Jefferson Lab which measured H(e,e’) and D(e,e’) inclusive cross
sections using the new Super High Momentum Spectrometer (SHMS).
The experiment focused on the intermediate Q2 , large Bjorken x, region where
existing world data is sparse and/or the statistical uncertainites are large.
This new data will better constrain parton distribution function (PDF)
fits, test quark-hadron duality at higher Q2 , improve DIS and resonance
modeling, and provide insight on the valence quark dynamics at large x.
New results of the deuterium to proton structure functions, F2D/F2P , will
be shown along with a brief discription of the analysis, its impact on PDF
fits and preliminary quark hadron duality studies.
