Perturbative matching of continuum and lattice quasi-distributions
Tomomi Ishikawa
Matching of the quasi parton distribution functions between continuum and lattice is addressed using lattice perturbation theory specifically with Wilson-type fermions. The matchin…
Parton distributions and lattice QCD calculations: a community white paper
Huey-Wen Lin, Emanuele R. Nocera, Fred Olness +29
In the framework of quantum chromodynamics (QCD), parton distribution functions (PDFs) quantify how the momentum and spin of a hadron are divided among its quark and gluon constitu…
Gaussian-weighted Parton Quasi-distribution
Tomomi Ishikawa, Luchang Jin, Huey-Wen Lin +4
We propose a revised definition of quasi-distributions within the framework of large-momentum effective theory (LaMET) that improves convergence towards the large-momentum limit. S…
Symmetry Properties of Nonlocal Quark Bilinear Operators on a Lattice
Jiunn-Wei Chen, Tomomi Ishikawa, Luchang Jin +3
Using symmetry properties, we determine the mixing pattern of a class of nonlocal quark bilinear operators containing a straight Wilson line along a spatial direction. We confirm t…
Improved Parton Distribution Functions at Physical Pion Mass
Huey-Wen Lin, Jiunn-Wei Chen, Tomomi Ishikawa +1
We present the first lattice results on isovector unpolarized and longitudinally polarized parton distribution functions (PDFs) at physical pion mass. The PDFs are obtained using t…
On the Renormalizability of Quasi Parton Distribution Functions
Tomomi Ishikawa, Yan-Qing Ma, Jian-Wei Qiu +1
Quasi-parton distribution functions have received a lot of attentions in both perturbative QCD and lattice QCD communities in recent years because they not only carry good informat…
