%0 Journal Article %T Large x physics: recent results and future plans %A Roy J. Holt %J Physics %D 2013 %I arXiv %X The valence region is exceedingly important in hadron physics since this region not only defines a hadron but also is an excellent discriminator of nucleon structure models. Present uncertainties in light quark distribution functions at high x could also impact high energy physics. Here we will describe a new generation of experiments at Jefferson Lab that is aimed at the high x region of the nucleon. It is noted that the proposed Electron Ion Collider could explore the high x regime. %U http://arxiv.org/abs/1311.1527v1
