From QCD sum rules to HQET sum rules: Heavy-quark limit of four-quark operator matrix elements
En-Qi Wu, Yi-Peng Xing, Zhen-Xing Zhao +1
Heavy quark expansion theory provides the standard theoretical framework for understanding the lifetimes of weakly decaying heavy-flavor hadrons. Within this framework, the matrix…
Implications on CP violation of charmless three body decays of bottom baryon from the U-spin analysis
Wei Wang, Zhi-Peng Xing, Zhen-Xing Zhao
Motivated by recent LHCb measurements of CP violation in three-body decays, we conduct an analysis of CP asymmetry in three-body decays of bottom baryons utilizing U-spin sy…
Weak decays of triply heavy baryons in the light-front approach
Zhen-Xing Zhao, Qi Yang
In this work, we investigate the weak decays of ground-state triply heavy baryons. We first obtain the form factors using the light-front quark model in the three-quark picture, an…
Light-cone sum rules study on the purely non-factorizable decay
Yu-Ji Shi, Zhen-Xing Zhao
We investigate the purely non-factorizable decay using light-cone sum rules. To extract the decay amplitudes, a three-point correlation function is defin…
