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…

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…

Role of sea quarks in the nucleon transverse spin
Chunhua Zeng, Hongxin Dong, Tianbo Liu +2
We present a phenomenological extraction of transversity distribution functions and Collins fragmentation functions by simultaneously fitting to semi-inclusive deep inelastic scatt…
