Factorization formula connecting the $Λ_{Q}$ 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 $Ω_{c}^{0} \to Ω^{-} (π^{+}, ρ^{+}, l^{+} ν_{l})$

Yu-Ji Shi, Jun Zeng

We study the weak decays of the charmed baryon $Ω_{c}^{0}$ to the $Ω^{-}$ 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…
