Extraction of transverse-momentum-dependent helicity distributions of the nucleon

Ke Yang, Tianbo Liu, Bo-Qiang Ma +3

We present an updated global analysis of the transverse-momentum-dependent (TMD) helicity distributions of the nucleon from measurements of the longitudinal double-spin asymmetry $…

Hyperon-Nucleon Spectrometer

Xiaozhi Bai, Xu Cao, Zhe Cao +237

Chirality lies at the heart of low-energy QCD, governing the symmetry structure that shapes hadron masses and strong interaction dynamics. Among the most compelling open questions…

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…

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…
