The strong decays of $\Xi$ baryons up to N=2 shell were studied in a chiral quark model. The strong decay properties of these well-established ground decuplet baryons were reasonably described. We found that (i) $\Xi(1690)$ and $\Xi(1820)$…

A study of the baryon excitation spectra provides a deep insight into the inner structure of baryons. Most of the world-wide efforts have been directed towards $N^*$ and $\Delta^*$ spectroscopy. Complementary data from double and triple…

The mass spectrum and magnetic moments of \Xi and \Omega baryon resonances are investigated in the bound state approach of the Skyrme model. The empirical hyperon spectrum shows that several hyperon resonances share a pattern of…

Mass spectra of heavy baryons are calculated in the heavy-quark--light-diquark picture in the framework of the QCD-motivated relativistic quark model. The dynamics of light quarks in the diquark as well as the dynamics of the heavy quark…

The resonance state of $\Delta$ baryon existing in four isospin ($I=\frac{3}{2}$) states, has been studied using Hypercentral Constituent Quark Model (hCQM) with a simple linear potential with added first order correction. The calculated…

The framework of phenomenological quark-antiquark potential (Coulomb plus linear confinement) model with the Gaussian wave function is used for detailed study of masses of the ground, orbitally and radially excited states of heavy-light…

The resonance mass spectra have been studied through a non-relativistic hypercentral Constituent Quark Model (hCQM) using a linear potential. Also, the effects of higher order correction terms (${\cal{O}}(\frac{1}{m})$,…

We present a study of mass spectra and electromagnetic couplings of $S$- and $P$-wave heavy baryons in the framework of a non-relativistic harmonic oscillator quark model. Particular attention is paid to the properties of heavy cascade…

The aim of the present article is investigation of the newly observed resonances $\Xi_c(2923)^{0}$, $\Xi_c(2939)^{0}$, and $\Xi_c(2965)^{0}$ which are real candidates to charm-strange baryons. To this end, we calculate the mass and pole…

Very recently, LHCb Collaboration observed that two new $\Omega_{c}^{0}$ states decay into $\Xi^{+}_{c}K^{-}$ with masses of about $3185$ MeV and $3327$ MeV. However, their spin parity quantum numbers $J^{P}$ have not been determined. In…

In this two part series a chiral confining model of baryons is used to describe low--lying negative parity resonances $N^*$, $\Delta^*$, $\Lambda^*$ and $\Sigma^*$ in the mean field approximation. A physical baryon in this model consists of…

We calculate the mass spectra of $\Lambda_{c}$, $\Xi_{c}$, $\Sigma_{c}$, $\Xi_{c}^{'}$, and $\Omega_{c}$ baryons in the framework of quark-diquark configuration using relativistic flux tube model. The spin-dependent interactions are…

In this work, we enumerated the mass spectra of the experimentally unobserved $1F$-wave states with the the orbital angular momentum $L$ = 3 for the singly heavy $\Sigma_{Q}$, $\Xi^{\prime}_{Q}$, and $\Omega_{Q}$ $(Q=c, b)$ baryons in the…

Various model-independent aspects of the $\bar{K} N \to K \Xi$ reaction are investigated, starting from the determination of the most general structure of the reaction amplitude for $\Xi$ baryons with $J^P=\frac12^\pm$ and $\frac32^\pm$ and…

In this work, we perform a systematic study of the mass spectra, the root mean square(r.m.s.) radii and the radial density distributions of the doubly charmed baryons $\Xi_{cc}$ and $\Omega_{cc}$. The calculations are carried out in the…

Measurements on the weak decay asymmetry parameters of charmed baryon, say $\Xi_c$, provide more information on the $W$-emission and $W$-exchange mechanisms controlled by the strong and weak interactions. Taking advantage of the spin…

Hadron spectra and other properties of quark systems are studied in the framework of a non-relativistic spin-independent phenomenological model. The chosen confining potential is harmonic, which allowed us to obtain analytical solutions for…

$\Omega^{-}$ baryon with sss quarks has been scarcely observed in the experiments so far and has been exploited through many theoretical studies only. Here, an attempt has been made to explore properties of $\Omega$ with hypercentral…

We extract, from a quark model potential that reproduces the number and ordering of nonstrange baryonic resonances up to 2.3 GeV, the quantum numbers for the dominant configurations in the ground and first non-radial excited states. From…

The mass spectra of charmonia, bottomonia and B_c mesons are calculated in the framework of the QCD-motivated relativistic quark model based on the quasipotential approach. The dynamics of heavy quarks and antiquarks is treated fully…
