Kinematic enhancement for nucleon interpolators
Daniel Reitinger, Tobias Sizmann, Andreas Schäfer +2
The reliable treatment of highly boosted hadrons is crucial for many lattice QCD applications. For all these cases the kinematically enhanced interpolators promise very significant…
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…
Total Gluon Helicity Contribution to the Proton Spin from Lattice QCD
Dian-Jun Zhao, Long Chen, Hongxin Dong +8
We report a state-of-the-art lattice QCD calculation of the total gluon helicity contribution to the proton spin, . The calculation is done on ensembles with three different la…
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…
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…
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…
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…
First direct lattice-QCD calculation of the -dependence of the pion parton distribution function
Jian-Hui Zhang, Jiunn-Wei Chen, Luchang Jin +3
We present the first direct lattice-QCD calculation of the Bjorken- dependence of the valence quark distribution of the pion. Using large-momentum effective theory (LaMET), we c…
