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…
QCD sum rules study on weak decays
Yu-Ji Shi, Jun Zeng
We study the weak decays of the charmed baryon to the baryon within the framework of QCD sum rules. A three-point correlation function is defined for calculating eigh…
Probing heavy meson lightcone distribution amplitudes with heavy quark spin symmetry
Zhi-Fu Deng, Wei Wang, Yan-Bing Wei +1
Building on a previous work~\cite{Han:2024min}, we illustrate that the leading-twist light-cone distribution amplitudes (LCDAs) defined in heavy-quark effective theory (HQET) can b…
Revisiting mixing in QCD sum rules
Yu-Ji Shi, Jun Zeng, Zhi-Fu Deng
We investigate the mixing caused by the flavor symmetry breaking. The mixing angle is expressed by a matrix element induced by the…
QED contributions to the mixing
Zhi-Fu Deng, Yu-Ji Shi, Wei Wang +1
We explore the QED corrections to the mixing within the framework of light-front quark model (LFQM) in the three-quark picture. After explicitly investigating th…
