Transverse-Momentum-Dependent Parton Distribution Functions from Large-Momentum Effective Theory
Xiangdong Ji, Yizhuang Liu, Yu-Sheng Liu
We show that transverse-momentum-dependent parton distribution functions (TMDPDFs), important non-perturbative quantities for describing the properties of hadrons in high-energy sc…
TMD Soft Function from Large-Momentum Effective Theory
Xiangdong Ji, Yizhuang Liu, Yu-Sheng Liu
We study Euclidean formulations of the transverse-momentum-dependent (TMD) soft function, which is a cross section for soft gluon radiations involving color charges moving in two c…
Matching Quasi Generalized Parton Distributions in the RI/MOM scheme
Yu-Sheng Liu, Wei Wang, Ji Xu +4
Within the framework of large momentum effective theory (LaMET), genenaralized parton distributions (GPDs) can be extracted from lattice calculations of quasi-GPDs through a pertur…
Matching the Quasi Meson Distribution Amplitude in RI/MOM scheme
Yu-Sheng Liu, Wei Wang, Ji Xu +3
The -dependence of light-cone distribution amplitude (LCDA) can be directly calculated from a quasi distribution amplitude (DA) in lattice QCD within the framework of large-mome…
Nucleon Transversity Distribution at the Physical Pion Mass from Lattice QCD
Yu-Sheng Liu, Jiunn-Wei Chen, Luchang Jin +5
We report a state-of-the-art lattice calculation of the isovector quark transversity distribution of the proton at the physical pion mass. Within the framework of large-momentum ef…
Proton Isovector Helicity Distribution on the Lattice at Physical Pion Mass
Huey-Wen Lin, Jiunn-Wei Chen, Xiangdong Ji +6
We present a state-of-the-art calculation of the isovector quark helicity Bjorken- distribution in the proton using lattice-QCD ensembles at the physical pion mass. We compute q…
