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…
Lattice QCD calculation of charmed baryon decay constants at continuum limit and physical mass
Lei-Yi Li, Jie Ran, Meng-Chu Cai +10
We present the first principle calculation of charmed baryon decay constants employing 2+1 flavor gauge ensembles with lattice spacings ranging from 0.05 to 0.1 fm and pion masses…
A realistic method to access heavy meson light-cone distribution amplitudes from first-principle
Xue-Ying Han, Jun Hua, Xiangdong Ji +5
Lightcone distribution amplitudes (LCDAs) of heavy meson within heavy quark effective theory (HQET) are crucial for predicting physical observables in decays, but unfortunately…
Heavy meson lightcone distribution amplitudes from Lattice QCD

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…
Calculation of heavy meson light-cone distribution amplitudes from lattice QCD
Xue-Ying Han, Jun Hua, Xiangdong Ji +9
We develop an approach for calculating heavy quark effective theory (HQET) light-cone distribution amplitudes (LCDAs) by employing a sequential effective theory methodology. The th…
