Description
The quasi-PDF approach, proposed by Ji in 2013, is at the forefront of numerical calculation of partonic structure of strongly interacting systems from lattice QCD. This approach relies on the extraction of matrix elements of space-like operators for fast-moving hadrons. Such auxiliary quantities can be related to the light-cone PDFs through a perturbatively calculable matching coefficient. We explore the formalism of matching, for the first time, for the twist-3 PDFs $g_{T}(x)$, $e(x)$ and $h_{L}(x)$. In this talk, we address the theoretical aspects and the subtleties involved in the extraction of the matching coefficient due to the presence of the singular zero-mode contributions.
