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 firstprinciple 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.
