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.Comment: 10 pages, 6 figures, proceedings of the 39th International Symposium
