The traditional approach expresses moments of PDFs in terms of matrix elements of local operators, but these operators suffer from power-divergent mixing that stems from the hypercubic symmetry of the lattice regulator. I will introduce the gradient flow as a means to suppress this power-divergent mixing, at the expense of introducing a new physical scale in the continuum. I will highlight two approaches to dealing with this new scale that could ultimately lead to ab initio calculations of PDFs on the lattice.<br class="">_______________________________________________<br class="">Theory-seminars mailing list<br class=""><a href="mailto:Theory-seminars@jlab.org" class="">Theory-seminars@jlab.org</a><br class="">https://mailman.jlab.org/mailman/listinfo/theory-seminars<br class=""></div></blockquote></div><br class=""></div></div></body></html>
