论文摘要
ZEUS协作中的高$ x $数据用于在QCD的扰动状态中提取质子深处的Parton密度分布。数据主要限制了Quark Valence分布，并在其$ x $依赖性以及Up-Quark携带的动量上提出了新的结果。使用贝叶斯分析方法获得了结果，该方法可以用作未来的Parton密度提取的模型。
The high-$x$ data from the ZEUS Collaboration are used to extract parton density distributions of the proton deep in the perturbative regime of QCD. The data primarily constrain the up-quark valence distribution and new results are presented on its $x$-dependence as well as on the momentum carried by the up-quark. The results were obtained using Bayesian analysis methods which can serve as a model for future parton density extractions.
