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…
The transversity parton distribution function of the nucleon using the pseudo-distribution approach
Colin Egerer, Christos Kallidonis, Joseph Karpie +8
We present a determination of the non-singlet transversity parton distribution function (PDF) of the nucleon, normalized with respect to the tensor charge at GeV from l…
Unpolarized gluon distribution in the nucleon from lattice quantum chromodynamics
Tanjib Khan, Raza Sabbir Sufian, Joseph Karpie +9
In this study, we present a determination of the unpolarized gluon Ioffe-time distribution in the nucleon from a first principles lattice quantum chromodynamics calculation. We car…
