Description
Designing good schemes to connect bare operators used in Lattice-QCD to perturbatively defined schemes (such as MSbar) is crucial for Lattice-QCD calculations. Operators containing Wilson Lines (for example those required for a quasi-pdf) contain an additional power divergence in the length of the Wilson Line. In this talk, I'll introduce gauge invariant position-space renormalization schemes that do not require separate renormalization conditions for this power divergence.
