Proton's isovector PDF with updated analysis of large-momentum lattice data
Xiangdong Ji, Yushan Su
The proton's unpolarized parton distribution function (PDF) has been studied by a number of lattice QCD groups through large momentum expansion. However, due to lattice…
Large-Momentum Effective Theory's Asymptotic Extrapolation vs the Inverse Problem
Jiunn-Wei Chen, Xiang Gao, Jinchen He +10
Large-Momentum Effective Theory (LaMET) is a physics-guided systematic expansion to calculate light-cone parton distributions, including collinear (PDFs) and transverse-momentum-de…
Precision determination of nucleon iso-vector scalar and tensor charges at the physical point
Ji-Hao Wang, Zhi-Cheng Hu, Xiangdong Ji +4
We report a high precision calculation of the isospin vector charge of the nucleon using recently proposed ``blending" method which provides a high-precision stochastic e…
Lattice QCD Determination of the Collins-Soper Kernel in the Continuum and Physical Mass Limits
Jin-Xin Tan, Zhi-Chao Gong, Jun Hua +12
The Collins-Soper (CS) kernel governs the rapidity evolution of transverse-momentum-dependent (TMD) parton distributions, a cornerstone for QCD factorization and linking nucleon st…
Heavy meson lightcone distribution amplitudes from Lattice QCD
Xue-Ying Han, Jun Hua, Cai-Dian Lü +8
Lightcone distribution amplitudes (LCDAs) within the framework of heavy quark effective theory (HQET) play a crucial role in the theoretical description of weak decays of heavy bot…
Quark Transverse Spin-Momentum Correlation of the Nucleon from Lattice QCD: The Boer-Mulders Function
Lingquan Ma, Jun Hua, Andreas Schäfer +9
We present the first lattice QCD calculation of the quark transverse spin-momentum correlation, i.e., the naive time-reversal-odd Boer-Mulders function, of the nucleon, using large…
