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.
