Nonperturbative partonic quasidistributions of the pion from chiral quark models
Physics Letters B, 2017 We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the Nambu–Jona-Lasinio model and the Spectral Quark Model.

Quark matter and quark stars at finite temperature in Nambu–Jona-Lasinio model
European Physical Journal C: Particles and Fields, 2017 We extend the SU(3) Nambu–Jona-Lasinio (NJL) model to include two types of vector interaction. Using these two types of vector interaction in NJL model, we study the quark symmetry free energy in asymmetric quark matter, the constituent quark mass, the ...

Thermoelectric transport coefficients of quark matter
European Physical Journal C: Particles and Fields, 2022 A thermal gradient and/or a chemical potential gradient in a conducting medium can lead to an electric field, an effect known as thermoelectric effect or Seebeck effect.

Light-front holographic ρ-meson distributions in the momentum space
Journal of High Energy Physics, 2021 We present the leading-twist quark transverse momentum-dependent parton distribution functions (TMDs) for the spin-1 target, such as the ρ-meson, in the light-front framework.

Study of heavy quark conserving weak decays in the quark model
Physics Letters B, 2022 Within the framework of a constituent quark model, we investigate the heavy quark conserving weak decays of Ξc and Ξb. This process involves elementary transitions of us→du or s→udu¯ with the heavy quark as a spectator, while for the charmed baryon in ...

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 ...

New signals for vector-like down-type quark in U(1) of $$E_6$$ E6
European Physical Journal C: Particles and Fields, 2018 We consider the pair production of vector-like down-type quarks in an $$E_6$$ E6 motivated model, where each of the produced down-type vector-like quark decays into an ordinary Standard Model light quark and a singlet scalar.

Properties of color-flavor locked matter in a quasiparticle model
European Physical Journal C: Particles and Fields, 2023 We investigate the thermodynamical properties of color-flavor locked (CFL) quark matter at zero temperature, finite temperature, and strong magnetic field by using quasiparticle model. We find that considering CFL quark phase can significantly change the

The Effective Baryon–Baryon Potential with Configuration Mixing in Quark Models
UniverseThe effective baryon–baryon potential can be derived in the framework of the quark model. The configurations with different quark spatial distributions are mixed naturally when two baryons get close. The effect of configuration mixing in the chiral quark

Asymmetries of quark sea in nucleon
EPJ Web of Conferences, 2014 The effects of “quark sea” in determining the flavor structure of the octet baryons have been investigated in the chiral constituent quark model. The chiral constituent quark model is able to qualitatively generate the requisite amount of quark sea and ...
