Total Gluon Helicity Contribution to the Proton Spin from Lattice QCD
Dian-Jun Zhao, Long Chen, Hongxin Dong +8
We report a state-of-the-art lattice QCD calculation of the total gluon helicity contribution to the proton spin, . The calculation is done on ensembles with three different l…

Unpolarized gluon PDF of the nucleon from lattice QCD at physical point in the continuum limit
Chen Chen, Hongxin Dong, Liuming Liu +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…

Global analysis of Sivers and Collins asymmetries within the TMD factorization
Chunhua Zeng, Hongxin Dong, Tianbo Liue +2
We present a global analysis of Sivers functions, transversity distribution functions, and Collins fragmentation functions within the transverse momentum dependent factorization. T…
