Quasi-PDFs with twisted mass fermions

Understand

We discuss the recent progress in extracting partonic functions from the quasi-distribution approach, using twisted mass fermions.

• This concerns, among others, the investigation of several sources of systematic effects.
• Their careful analysis is a prerequisite to obtain precise determinations of PDFs from the lattice with realistic estimates of all uncertainties.
• In these proceedings, we shortly discuss systematic effects in the matching procedure.
