Description

The quasi-PDF approach has made it possible to extract the light-cone PDFs from lattice QCD. In this approach, one calculates matrix elements of space-like operators for boosted hadrons. Quasi-PDFs can be related to the light-cone PDFs through a perturbatively calculable matching coefficient. We address the matching for the very first time for the twist-3 PDFs $g_{T}(x)$ and $h_{L}(x)$. In this talk, we focus on potential complications in the matching due to the presence of singular zero-mode contributions.
