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…

Determination of the pseudoscalar decay constant from SU(2) with two fundamental flavors

Laurence Sebastian Bowes, Vincent Drach, Patrick Fritzsch +3

The SU(2) gauge group with two fundamental flavors is a candidate for a composite Higgs extension of the Standard Model. Central to Higgs phenomenology is a non-perturbative determ…

Exploiting stochastic locality in lattice QCD: hadronic observables and their uncertainties

Mattia Bruno, Marco Cè, Anthony Francis +4

Because of the mass gap, lattice QCD simulations exhibit stochastic locality: distant regions of the lattice fluctuate independently. There is a long history of exploiting this to…

Hadronic observables from master-field simulations

Marco Cè, Mattia Bruno, John Bulava +5

Substantial progress has been made recently in the generation of master-field ensembles. This has to be paired with efficient techniques to compute observables on gauge field confi…
