Low-lying singly heavy baryon states based on the rigorous calculation with the relativized quark model

Zhen-Yu Li, Guo-Liang Yu, Zhi-Gang Wang +1

In this work, the low-lying $6_{F}$ singly heavy baryon states with positive-parity are studied in detail in the framework of the relativized quark model by using the impr…

The semileptonic decays of $B_{Q_{1} Q_{2}} (\frac{1}{2}^{+}) \to B_{Q_{1}}^{*} (\frac{3}{2}^{+})$ in QCD sum rules

Guo-Liang Yu, Zhi-Gang Wang, Jie Lu +3

In the framework of QCD sum rules, we systematically analyze the weak transition process $\mathcal{B}_{Q_{1}Q_{2}}(\frac{1}{2}^{+})\rightarrow\mathcal{B}_{Q_{1}}^{*}(\frac{3}{2}^{+…

Spin-dependent interactions and fine structure in the negative-parity singly heavy baryons

Zhen-Yu Li, Guo-Liang Yu, Zhi-Gang Wang +1

In order to meet the high-precision measurement of the current baryon spectroscopy, for the first time, we rigorously analyze the spin-dependent interactions and the fine structure…
