我们提出了一个新的全球QCD分析的非极化部分子分布函数（PDF）和核效应，包括第一次从SeaQuest和马拉松实验的数据，除了从Tevatron和大型强子对撞机的高能弱玻色子生产数据。同时提取的PDF和核效应，我们研究的影响的SeaQuest和马拉松数据的光夸克海不对称性和EMC比的氘，氦，氚。
We present a new global QCD analysis of unpolarized parton distribution functions (PDFs) and nuclear effects including for the first time data from the SeaQuest and Marathon experiments in addition to high-energy weak-boson-production data from the Tevatron and Large Hadron Collider. Simultaneously extracting the PDFs and nuclear effects, we examine the impact of the SeaQuest and Marathon data on the light-quark sea asymmetry and the EMC ratios of deuterium, helium, and tritium.
