Moments of parton distributions functions of the pion from lattice QCD using gradient flow
Anthony Francis, Patrick Fritzsch, Rohith Karur +7
We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios …
Gradient flow for parton distribution functions: first application to the pion
Anthony Francis, Patrick Fritzsch, Robert V. Harlander +9
Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operator…
Probing higher moments of pion parton distribution functions
Anthony Francis, Patrick Fritzsch, Rohith Karur +7
We present the first numerical investigation of the method proposed in Ref. [1] to utilize gradient flow to obtain precise determinations of higher moments of PDFs from lattice QCD…
Machine learning mapping of lattice correlated data
Jangho Kim, Giovanni Pederiva, Andrea Shindler
We discuss a machine learning (ML) regression model to reduce the computational cost of disconnected diagrams in lattice QCD calculations. This method creates a mapping between the…
