Non-singlet quark helicity PDFs of the nucleon from pseudo-distributions
Robert G. Edwards, Colin Egerer, Joseph Karpie +9
The non-singlet helicity quark parton distribution functions (PDFs) of the nucleon are determined from lattice QCD, by jointly leveraging pseudo-distributions and the distillation…
Towards the determination of the gluon helicity distribution in the nucleon from lattice quantum chromodynamics
Colin Egerer, Bálint Joó, Joseph Karpie +10
We present the first exploratory lattice quantum chromodynamics (QCD) calculation of the polarized gluon Ioffe-time pseudo-distribution in the nucleon. The Ioffe-time pseudo-distri…
Lattice QCD and Particle Physics
Andreas S. Kronfeld, Tanmoy Bhattacharya, Thomas Blum +79
Contribution from the USQCD Collaboration to the Proceedings of the US Community Study on the Future of Particle Physics (Snowmass 2021).
A lattice QCD perspective on weak decays of b and c quarks Snowmass 2022 White Paper
Peter A. Boyle, Bipasha Chakraborty, Christine T. H. Davies +32
Lattice quantum chromodynamics has proven to be an indispensable method to determine nonperturbative strong contributions to weak decay processes. In this white paper for the Snowm…
Complementarity of experimental and lattice QCD data on pion parton distributions
P. C. Barry, C. Egerer, J. Karpie +8
We extract pion parton distribution functions (PDFs) in a Monte Carlo global QCD analysis of experimental data together with reduced Ioffe time pseudo-distributions and matrix elem…
A novel nonperturbative renormalization scheme for local operators
Anna Hasenfratz, Christopher J. Monahan, Matthew D. Rizik +2
The gradient flow exponentially suppresses ultraviolet field fluctuations and removes ultraviolet divergences (up to a multiplicative fermionic wavefunction renormalization). It ca…
