Parton Distribution Functions from Ioffe Time Pseudodistributions from Lattice Calculations: Approaching the Physical Point

Journal Article Joó, Bálint ; Karpie, Joseph ; Orginos, Kostas ; ... - Physical Review Letters

We present results for the unpolarized parton distribution function of the nucleon computed in lattice QCD at the physical pion mass. This is the first study of its kind employing the method of Ioffe time pseudodistributions. Beyond the reconstruction of the Bjorken-x dependence, we also extract the lowest moments of the distribution function using the small Ioffe time expansion of the Ioffe time pseudodistribution. We compare our findings with the pertinent phenomenological determinations.

Flavor decomposition of the nucleon unpolarized, helicity, and transversity parton distribution functions from lattice QCD simulations

Journal Article Alexandrou, Constantia ; Constantinou, Martha ; Hadjiyiannakou, Kyriakos ; ... - Physical Review D

We present results on the quark unpolarized, helicity and transversity parton distributions functions of the nucleon. We use the quasiparton distribution approach within the lattice QCD framework and perform the computation using an ensemble of twisted mass fermions with the strange and charm quark masses tuned to approximately their physical values and light quark masses giving pion mass of 260 MeV. We use hierarchical probing to evaluate the disconnected quark loops. We discuss identification of ground state dominance, the Fourier transform procedure and convergence with the momentum boost. We find nonzero results for the disconnected isoscalar and strange quark distributions.more »« less

Flavor nonsinglet parton distribution functions from lattice QCD at physical quark masses via the pseudodistribution approach

Journal Article Bhat, Manjunath ; Cichy, Krzysztof ; Constantinou, Martha ; ... - Physical Review D

One of the great challenges of QCD is to determine the partonic structure of the nucleon from first principles. In this work, we provide such a determination of the flavor nonsinglet (u ₋ d) unpolarized parton distribution function (PDF), utilizing the nonperturbative formulation of QCD on the lattice. We apply Radyushkin’s pseudodistribution approach to lattice results obtained using simulations with the light quark mass fixed to its physical value; this is the first ever attempt for this approach directly at the physical point. The extracted coordinate-space matrix elements are used to find the relevant physical Ioffe time distributions from a matching procedure. The full Bjorken-x dependence of PDFs is resolved using several reconstruction methods to tackle the ill-conditioned inverse problem encountered when using discrete lattice data. We consider both the valence distribution q_v and the combination with antiquarksmore »« less

Light-Cone Parton Distribution Functions from Lattice QCD

Journal Article Alexandrou, Constantia ; Cichy, Krzysztof ; Constantinou, Martha ; ... - Physical Review Letters

We extract parton distribution functions (PDFs) of the nucleon from lattice QCD using an ensemble of gauge field configurations simulated with light quark masses fixed to their physical values. Theoretical and algorithmic improvements that allow such a calculation include momentum smearing to reach large nucleon boosts with reduced statistical errors, nonperturbative renormalization, target mass corrections, and a novel modified matching of lattice QCD results to connect to what is extracted from experimental measurements. We give results on the unpolarized and helicity PDFs in the modified minimal subtraction scheme at a scale of 2 GeV and reproduce the main features ofmore »« less
