Description
Pseudo- and quasi-parton distribution functions (PDFs) defined through space-like bilocal operators allow for direct access to the PDFs from first principles in lattice gauge theory. However, this formalism currently leaves the small Bjorken $x$ regime inaccessible. With the future Electron-Ion Collider in mind, it is timely to study the PDFs at small-$x$. In a previous calculation, we showed that the gluon pseudo and quasi PDFs have distinct behavior at small-$x$. It is known that the behavior of the quark distribution at small-$x$ is not directly related to that of the gluon PDF, as previous research has shown. In this talk, I will present the calculation of the quark pseudo- and quasi-PDFs in the high-energy limit, and show that they too have distinct behavior at small-$x$.
