Recently, three new states of $$\varXi _c^0$$ Ξ c 0 were observed in the invariant mass spectrum of $$\varLambda ^+_cK^-$$ Λ c + K - by LHCb collaboration. In this work, we use a chiral quark model to investigate these three exited states with the help of Gaussian expansion method both in three-quark structure and in five-quark structure with all possible quantum numbers $$IJ^P=\frac{1}{2}(\frac{1}{2})^-$$ I J P = 1 2 ( 1 2 ) - , $$\frac{1}{2}(\frac{3}{2})^-$$ 1 2 ( 3 2 ) - , $$\frac{1}{2… 


Flavor structure of the excited baryon spectra from lattice QCD
Excited state spectra are calculated using lattice QCD for baryons that can be formed from $u$, $d$ and $s$ quarks, namely the $N$, $$\Delta$$, $$\Lambda$$, $$\Sigma$$, $$\Xi$$ and $$\Omega$$
Description of the $$\Xi _c$$Ξc and $$\Xi _b$$Ξb states as molecular states
In this work we study several $$\Xi _c$$Ξc and $$\Xi _b$$Ξb states dynamically generated from the meson–baryon interaction in coupled channels, using an extension of the local hidden gauge approach
Y(4626) in a chiral constituent quark model
Recently, Belle Collaboration reported a new exotic state $Y(4620)$ with mass at 4625.9 MeV in the positronium annihilation process. Inspired by experiment, we study the tetraquark system
Compact ssscc¯ pentaquark states predicted by a quark model
Abstract Several compact s s s c c ¯ pentaquark resonances are predicted in a potential quark model. The Hamiltonian is the best available one, which reproduces the masses of the low-lying charmed
Gaussian expansion method for few-body systems
Abstract We review our method of calculation, Gaussian Expansion Method (GEM), for bound and scattering states of few-body systems. The method was proposed in 1988 and has been applied to a variety
Dynamically generated open-charm baryons beyond the zero-range approximation
The interaction of the low-lying pseudoscalar mesons with the ground-state baryons in the charm sector is studied within a coupled-channel approach using a $t$-channel vector-exchange driving force.
Constituent quark model study of the meson spectra
The spectrum is studied in a generalized constituent quark model constrained in the study of the NN phenomenology and the baryon spectrum. An overall good fit to the available experimental data is
Quark-model study of few-baryon systems
We review the application of non-relativistic constituent quark models to study one, two and three non-strange baryon systems. We present results for the baryon spectra, potentials and observables of
Resonance state lifetimes from stabilization graphs
The stabilization method has been used by many researchers for computing energies and, in some cases, widths of metastable states arising in electron–atom and electron–molecule interactions. In the
A schematic model of baryons and mesons
The bootstrap model for strongly interacting particles described in terms of the broken eightiold way is discussed to determine algebraic properties of the interactions with scattering amplitudes on
