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…

Using the Hypercentral Constituent Quark Model (hCQM), the mass spectra of doubly heavy baryons $\Xi_{cb}$ and $\Xi_{bb}$ are determined. The model describes an interaction inside the baryonic system. Screened potential has been considered…

In the framework of a non-relativistic quark model, the mass spectra of the ground and excited states of doubly heavy $\Xi$ and $\Omega$ baryons are calculated. We estimate the mass difference between the $ \Omega $ and corresponding $ \Xi…

In this article, we study the mass spectra of baryons containing two heavy quarks; charm-charm ($cc$) and bottom-charm ($bc$) with a light quark ($u,d,s$) within the framework of Regge phenomenology. With the assumption of linear Regge…

We present the mass spectra of radial and orbital excited states of singly heavy bottom baryons; $\Sigma_{b}^{+}, \Sigma_{b}^-, \Xi_b^-, \Xi_b^0, \Lambda_b^0$ and $\Omega_b^-$. The QCD motivated hypercentral quark model is employed for the…

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}^*$, $…

In this study, since the doubly heavy baryons masses are experimentally unknown (except and ), we present the ground state masses and the positive and negative parity excited state masses of doubly heavy baryons. For this purpose, we have…
