Unpolarized gluon PDF of the nucleon from lattice QCD at physical point in the continuum limit
Chen Chen, Chunhua Zeng, Hongxin Dong +8
We report a state-of-the-art lattice QCD calculation of the nucleon unpolarized gluon parton distribution function employing large-momentum effective theory. The calculation is car…

Regularization Prescription for the Mixing Between Nonlocal Gluon and Quark Operators
Yao Ji, Zhuoyi Pang, Fei Yao +1
It is well-known that in the study of mixing between nonlocal gluon and quark bilinear operators there exists an ambiguity when relating coordinate space and momentum space results…

Extracting Meson Distribution Amplitudes from Nonlocal Euclidean Correlations at Next-to-Next-to-Leading Order
Yao Ji, Fei Yao, Jian-Hui Zhang
We present the first complete result for the next-to-next-to-leading order (NNLO) hard matching kernel indispensable for a precision extraction of light meson distribution amplitud…
