论文摘要
我们从晶格QCD数据中提取两个非字节核分布函数，以减少Ioffe-time pseudoDodistriptions。我们在NNPDF框架内进行了此类分析，考虑了来自不同晶格集合的数据，并详细讨论了对拟合中涉及的不同系统学源的处理。我们介绍了一种处理系统学的食谱，并使用它来执行我们的轻锥PDF的提取。
We extract two nonsinglet nucleon Parton Distribution Functions from lattice QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis within the NNPDF framework, considering data coming from different lattice ensembles and discussing in detail the treatment of the different source of systematics involved in the fit. We introduce a recipe for taking care of systematics and use it to perform our extraction of light-cone PDFs.
