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…

First Extraction of Transverse Momentum Dependent Helicity Distributions
Ke Yang, Tianbo Liu, Peng Sun +2
We report on the first global analysis of transverse momentum dependent helicity distributions of the proton. The analysis is performed at next-to-leading order with the evolution…

Extraction of trans-helicity worm-gear distributions and opportunities at the Electron-Ion Collider in China
Ke Yang, Tianbo Liu, Peng Sun +2
We present a global analysis of the trans-helicity worm-gear distribution function, , by fitting the longitudinal-transverse double spin asymmetry data of the semi-in…
