论文摘要
对核子的党党结构的精确探索是高能量物理学的最重要目标之一。近年来，有可能通过第一原则QCD调查来解决这个主题。在本次演讲中，我们关注所谓的伪分布方法，以确定ISOVECTOR非偏振PDF。特别是，我们采用三个晶格间距来研究离散效应，并在连续性极限下以约370 meV的速度提取分布。同样，我们首次使用伪PDFS，我们探索了从伪锥分布到轻锥分布的2环匹配的效果。
Precise exploration of the partonic structure of the nucleon is one of the most important aims of high-energy physics. In recent years, it has become possible to address this topic with first-principle lattice QCD investigations. In this talk, we focus on the so-called pseudo-distribution approach to determine the isovector unpolarized PDFs. In particular, we employ three lattice spacings to study discretization effects and extract the distributions in the continuum limit, at a pion mass of around 370 MeV. Also, for the first time with pseudo-PDFs, we explore effects of the 2-loop matching from pseudo- to light-cone distributions.
