In this study, considering that the $\Xi_b (6227)$ state is in molecular structure, the magnetic moment of this state is extracted in the light-cone QCD sum rules. The numerical result is obtained as $\mu_{\Xi_b}= 0.12 \pm 0.03~\mu_N$. The…

We present an analysis of the newly observed pentaquark $P_c(4312)^+$ to shed light on its quantum numbers. To do that, the QCD sum rule approach is used. The measured mass of this particle is close to $\Sigma_c^{++}\bar{D}^-$ threshold and…

In this article, we tentatively assign the $P_c(4312)$ to be the $\bar{D}\Sigma_c$ pentaquark molecular state with the spin-parity $J^P={\frac{1}{2}}^-$, and discuss the factorizable and non-factorizable contributions in the two-point QCD…

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