Semi-leptonic form factors of $Ξ_{c} \to Ξ$ in QCD sum rules

Zhen-Xing Zhao, Xiao-Yu Sun, Fu-Wei Zhang +2

There exists a significant deviation between the most recent Lattice QCD simulation and experimental measurement by Belle for $Ξ_{c}^{0} \to Ξ^{-} ℓ^{+} ν_{ℓ}$ . In this work, we…

On the four-quark operator matrix elements for the lifetime of $Λ_{b}$

Zhen-Xing Zhao, Xiao-Yu Sun, Fu-Wei Zhang +1

Heavy quark expansion can nicely explain the lifetime of $Λ_{b}$ . However, there still exist sizable uncertainties from the four-quark operator matrix elements of $Λ_{b}$ in $1/m_{…
