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…
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…
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…
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…
