论文摘要
我们介绍了在物理亲质量下在晶格QCD中计算的核子的不偏离的Part型分布功能的结果。这是采用Ioffe Time伪分发方法的第一个研究。除了重建Bjorken- $ x $依赖性,我们还使用Ioffe Time Pseudo-Distribution的小型IOFFE时间扩展提取了分配功能的最低时刻。我们将我们的发现与相关的现象学决定进行了比较。
We present results for the unpolarized parton distribution function of the nucleon computed in lattice QCD at the physical pion mass. This is the first study of its kind employing the method of Ioffe time pseudo-distributions. Beyond the reconstruction of the Bjorken-$x$ dependence we also extract the lowest moments of the distribution function using the small Ioffe time expansion of the Ioffe time pseudo-distribution. We compare our findings with the pertinent phenomenological determinations.
