Partial decay widths of $P_{c} (4312)$ as a $D ˉ Σ_{c}$ molecular state

Yong-Jiang Xu, Chun-Yu Cui, Yong-Lu Liu +1

In the present work, the partial decay widths of $P_{c} (4312)$ to $η_{c} p$ and $J / ψ p$ are investigated with the QCD sum rule method under the assumption that $P_{c} (4312)$ is a $\…

$η_{b} B B^{*}$ vertex from QCD sum rules

Chun-Yu Cui, Yong-Lu Liu, Ming-Qiu Huang

The form factor and the coupling constant in the $η_{b} B B^{*}$ vertex are evaluated in the framework of three-point QCD sum rules. The correlation functions responsible for the…
