This study employs QCD sum rules to predict the masses and residues of spin-$\frac {3}{2} $ doubly heavy baryons including two heavy quarks (c and/or b) and one light quark, specifically focusing on $ \Xi_{cc}^*$, $ \Xi_{bc}^*$, $…
Strong decays of $\Xi_c$ baryons with radial or orbital excitations with positive parity have been studied in a $^3P_0$ model. As candidates of these $Xi_c$, possible configurations and $J^P$ of $\Xi_c(2930)$, $\Xi_c(2980)$, $\Xi_c(3055)$,…
We calculate the masses and residues of triply heavy baryons with spin-3/2, including $\Omega^*_{ccc}$, $\Omega^*_{ccb}$, $\Omega^*_{bbc}$ and $\Omega^*_{bbb}$, using the QCD sum rules method. Our calculations primarily focus on obtaining…

The LHCb Collaboration recently observed five narrow $\Omega_c^{0}$ resonances, and measured their masses and widths through the decays $ \Omega_c^{0} \to \Xi_c^{+}K^{-}$. Motivated by this discovery, and also by the fact that the…

Our study focuses on the $\Lambda$-type P-wave bottom baryon states with the spin-parity $J^P=\frac{1}{2}^-$, $\frac{3}{2}^-$. We introduce an explicit P-wave between the two light quarks in the interpolating currents (and the two light…
In this work, the strong decay behaviors of the $\lambda-$mode low-lying $\Xi_{b}$ and $\Xi_{b}^\prime$ baryons are investigated within the $^3P_0$ model. Our results suggest that all of the low-lying $\bar 3_F$ states $\Xi_b(2S)$,…

The LHCb experiment has recently reported two excited $\Omega_c$ resonances decaying to $\Xi_c^+ K^-$, with masses about 3185 and 3327 MeV. We discuss their assignment to $2S_{1/2}$ and $2S_{3/2}$ states, which can be compared with masses…

LHCb Collaboration first observed a doubly charmed baryon $\Xi^{++}_{cc}$ in the $\Lambda^{+}_{c}K^{-}\pi^{+}\pi^{+}$ decay with a mass of $3621.40\pm0.72\pm0.27$ MeV. In this paper, we enumerated the mass spectra of the radial and orbital…
The $\Xi_b(6227)$ baryon with the quantum number $J^P=1/2^{-}$ is considered as a molecular state composed of a $\Sigma_b$ baryon and $\bar{K}$ meson. The partial decay widths of the $\Sigma_b\bar{K}$ molecular state into $\Xi_b\gamma$ and…
The single charmed excited $\Xi_c(2930)$ state was discovered many years ago by BABAR collaboration and recently confirmed by Belle experiment. However, both of these experiments, unfortunately, could not fix the quantum numbers of this…
