1. Pion valence quark distribution from matrix element calculated in lattice QCD / Sufian, Raza Sabbir ; Karpie, Joseph ; Egerer, Colin ; Orginos, Kostas ; et al
We present the first exploratory lattice QCD calculation of the pion valence quark distribution extracted from spatially separated current-current correlations in coordinate space. [...]

2. Reconstructing parton distribution functions from Ioffe time data: from Bayesian methods to neural networks / Karpie, Joseph ; Orginos, Kostas ; Rothkopf, Alexander ; Zafeiropoulos, Savvas
The computation of the parton distribution functions (PDF) or distribution amplitudes (DA) of hadrons from first principles lattice QCD constitutes a central open problem in high energy nuclear physics. [...]

3. Moments of Ioffe time parton distribution functions from non-local matrix elements / Karpie, Joseph ; Orginos, Kostas ; Zafeiropoulos, Savvas
We examine the relation of moments of parton distribution functions to matrix elements of non-local operators computed in lattice quantum chromodynamics. [...]

4. Scalar, Axial, and Tensor Interactions of Light Nuclei from Lattice QCD / Chang, Emmanuel ; Davoudi, Zohreh ; Detmold, William ; Gambhir, Arjun S. ; et al
Complete flavor decompositions of the matrix elements of the scalar, axial, and tensor currents in the proton, deuteron, diproton, and He3 at SU(3)-symmetric values of the quark masses corresponding to a pion mass mπ806 MeV are determined using lattice quantum chromodynamics. [...]

5. Quasi parton distributions and the gradient flow / Monahan, Christopher ; Orginos, Kostas
We propose a new approach to determining quasi parton distribution functions (PDFs) from lattice quantum chromodynamics. [...]
