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…

Semileptonic $s \to u$ decays of singly heavy baryons

Yi-Peng Xing, Xiao-Qian Jiang, Zhen-Xing Zhao

$s \to u$ weak decays of heavy flavor hadrons play a unique role in the field of heavy flavor physics. In this work, we investigate semileptonic $s \to u$ decays of singly heavy bary…
