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 functions…
LQCDMaster: Agentic Scientific Computing for Lattice Quantum Chromodynamics Research
Haofei Gao, Tingjia Miao, Wenkai Jin +12
Lattice quantum chromodynamics (LQCD) provides a first-principles framework for computing hadronic observables, but its practical use remains limited by the substantial expertise r…
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…

Tong-Wei Lin, Zun-Xian Zhang, Mengchu Cai +8
We investigate the impact of including a dynamical charm quark on the properties of light hadrons. Our study compares the calculations performed on 2+1+1 flavor (HISQ fermion) ense…
Comparison of the mixed-fermion-action Effects using different fermion and gauge actions with 2+1 and 2+1+1 flavors
Zun-Xian Zhang, Mengchu Cai, Bolun Hu +4
The leading-order low-energy constant in mixed-action chiral perturbation theory is calculated using -flavor gauge ensembles with HISQ fermions and a tadpole-i…
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…
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…
Hybrid renormalization for distribution amplitude of a light baryon in large momentum effective theory
Haoyang Bai, Jun Hua, Xiangdong Ji +9
Lightcone distribution amplitudes for a light baryon can be extracted through the simulation of the quasi-distribution amplitudes (quasi-DAs) on the lattice. We implement the hybri…
Realization of all-to-all fermion propagator for the first principle high accuracy strong interaction prediction
Zhi-Cheng Hu, Ji-Hao Wang, Xiangyu Jiang +4
We propose a ``blending" algorithm that projects the all-to-all fermion propagator onto spatial low-frequency modes (LFM) combines the projection with a stochastic estimate of spat…
