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 $I^_{Q}$ 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…

QCD sum rules study on weak decays $I^c ◯_{c}^{0} \to I^c ◯^{-} (I ¨ ^{+}, I ¨ ^{+}, l^{+} I^½_{l})$

Yu-Ji Shi, Jun Zeng

We study the weak decays of the charmed baryon $I^c ◯_{c}^{0}$ to the $I^c ◯^{-}$ baryon within the framework of QCD sum rules. A three-point correlation function is defined for calculating ei…
