Abstract
We present a calculation of the bare quasi-PDF (qPDF) of the pion. We perform these calculations using the HotQCD HISQ gauge ensemble for our sea quarks along with a Wilson-Clover valence quark action. Our lattice size is $48^3\times64$, our lattice spacing is set at a = 0.06 fm, and our pion mass is tuned to 300 MeV.
Utilizing momentum smearing techniques, we compute the bare qPDF boosted up to momentum 1.72 GeV. In addition we explore excited state contamination of the three-point correlator.
