Baryon Light-Cone Distribution Amplitudes from Lattice QCD: Formalism, Renormalization, Extrapolation, and Matching
Mu-Hua Zhang, Haoyang Bai, Min-Huan Chu +11
Baryon light-cone distribution amplitudes (LCDAs) are inherently multidimensional objects parametrized by two independent longitudinal momentum fractions, making their first-princi…
Complete Access to Leading-Twist -Baryon Light-Cone Distribution Amplitudes from Lattice QCD
Mu-Hua Zhang, Haoyang Bai, Min-Huan Chu +11
We report the first complete lattice-QCD determination of the leading-twist light-cone distribution amplitudes (LCDAs) of the baryon, obtained as full two-dimensional function…
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…
Continuum-Limit HQET LCDAs from Lattice QCD for Tightening B Decay Uncertainties
Xue-Ying Han, Hao-Fei Gao, Jun Hua +15
Heavy meson HQET light-cone distribution amplitudes (LCDAs) are critical for precision predictions of meson weak decays, but currently are one of dominant theoretical uncertain…
Determination of heavy meson light-cone distribution amplitudes: theoretical framework and lattice simulations
Hao-Fei Gao, Xue-Ying Han, Jun Hua +15
We present a first-principles determination of heavy meson light-cone distribution amplitudes (LCDAs) from lattice QCD in the continuum limit, improving substantially on our previo…
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…
