The unquenched quark model [PDF]
EPJ Web of Conferences, 2015 In this contribution, we briefly discuss the results for charmonium and bottomonium spectra with self-energy corrections in the unquenched quark model, due to the coupling to the meson-meson continuum The UQM formalism can be extended to include also the

Tetra- and Penta-Quark Structures in the Constituent Quark Model [PDF]
Symmetry, 2020 With the development of high energy physics experiments, a large amount of exotic states in the hadronic sector have been observed. In order to shed some light on the nature of the tetraquark and pentaquark candidates, a constituent quark model, along with the Gaussian expansion method, has been employed systematically in real- and complex-range ...

EPJ Web of Conferences, 2012 With the advance of experiment, many high excited states of meson are identified. It is found that many of them are difficult to fit into conventional q$ar{q}$q¯ meson spectra. Various explanations are proposed.

Fully Heavy Tetraquark Spectroscopy in the Relativistic Quark Model [PDF]
Symmetry, 2022 Masses of the ground and excited (1P, 2S, 1D, 2P, 3S) states of the fully heavy tetraquarks, composed of charm (c) and bottom (b) quarks and antiquarks, are calculated in the diquark–antidiquark picture within the relativistic quark model based on the ...

Heavy Tetraquarks in the Relativistic Quark Model [PDF]
Universe, 2021 We give a review of the calculations of the masses of tetraquarks with two and four heavy quarks in the framework of the relativistic quark model based on the quasipotential approach and QCD.

Relativistic corrections to decays of heavy baryons in the quark model [PDF]
Physical Review D, 2021 We investigate relativistic corrections of an order 1 /m 2 , where m is the constituent quark mass, to heavy baryon decays by emitting one pseudoscalar meson in the quark model.

Tetraquarks and Pentaquarks from Quark Model Perspective
Symmetry, 2023 According to the classification of the quark model, the hadrons going beyond three-quark baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons have been observed since 2003, some of which exhibit exotic behaviors.

Study of Hidden-Charm and Hidden-Bottom Pentaquark Resonances in the Quark Model
Universe, 2023 Inspired by the LHCb observation of hidden-charm pentaquarks, i.e., Pc(4312), Pc(4440), and Pc(4457) in the J/ψp invariant mass spectrum, a calculation of the J/ψp scattering cross-section was performed using the quark-delocalization color screening ...

Masses of fully heavy tetraquarks $$QQ {\bar{Q}} {\bar{Q}}$$ in an extended relativized quark model [PDF]
, 2020 Inspired by recent measurement of possible fully charmed tetraquarks in LHCb Collaboration, we investigate the mass spectra of fully heavy tetraquarks $QQ \bar Q \bar Q$ in an extended relativized quark model.

Quark Structure of the X (4500), X (4700) and χc(4P,5P) States
Frontiers in Physics, 2021 We study some of the main properties (masses and open-flavor strong decay widths) of 4P and 5P charmonia. While there are two candidates for the χc0(4P,5P) states, the X(4500) and X(4700), the properties of the other members of the χc(4P,5P) multiplets ...
