Accessing the HQET B-Meson Shape Function from a LaMET Quasi-Shape Function
Ao-Sheng Xiong, Jun Ding, Ji Xu +2
The shape function and the light-cone distribution amplitude of heavy meson jointly characterize the nonperturbative structure of the heavy meson on the light-cone, with the former…

Factorization formula connecting the LCDA in QCD and boosted HQET
Yu-Ji Shi, Jun Zeng
Light-cone distribution amplitudes (LCDAs) are essential to precision phenomenology in heavy baryon decays. In this work, we derive a factorization formula connecting the leading-t…
