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 ...

Spectroscopy of higher bottomonia
EPJ Web of Conferences, 2015 In this contribution, we discuss our recent unquenched quark model results for the spectrum of bb̄ mesons with self energy corrections, due to the coupling to the meson-meson continuum.

Iranian Journal of Physics Research, 2009 In this research, we are going to study the QCD penguin structure and calculate the second order approximation. The amplitude of decays related to QCD penguin in the quark model up to the first and second orders were calculated.

Correspondence between QCD sum rules and constituent quark models [PDF]
Eur.Phys.J. C37 (2004) 437-444, 2004 We compare two widely used approaches to the description of hadron properties: QCD sum rules and constituent quark models. Making use of the dispersion formulation of the quark model, we show that both approaches lead to similar spectral representations for hadron observables with an important difference that quark model is based on Feynman diagrams ...

Neutrino emissivities in 2SC color-superconducting quark matter [PDF]
Phys.Part.Nucl.39:1163-1166,2008, 2007 The phase structure and equation of state for two-flavor quark matter under compact star constraints is studied within a nonlocal chiral quark model. Chiral symmetry breaking leads to rather large, density dependent quark masses at the phase transition to quark matter.

Heavy quark limit in the light front quark model [PDF]
, 1998 An explicit relativistic light-front model is presented which gives the momentum transfer dependent form factors of weak hadronic currents among heavy pseudoscalar and vector mesons in the whole accessible kinematical region $0\leq q^2 \leq q^2_{\max} $.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning
Advanced Quantum Technologies, EarlyView.The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...
