The Short Range Mechanism of N-N interaction in the Extended Chiral SU(3) Quark Model [PDF]
, 2004 We give the comparisons between the chiral SU(3) quark model and the extended chiral SU(3) quark model. The results show that the phase shifts of NN scattering are very similar.

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.

The spin-symmetry of the quark model [PDF]
The European Physical Journal C, 1999 Corrections to the exact heavy--quark symmetry results are expected to follow the $1/m_{Q}$ mass effect of the heavy--quark. We show, by an explicit calculation, that there is something other than the mass effect that suppresses the breaking of the spin symmetry.

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

Hyperon Polarization in a Quark-Quark Scattering Model [PDF]
AIP Conference Proceedings, 2007 A continuing mystery in particle physics is the large polarization observed in inclusive hyperon production in high energy p-p collisions. In this paper the authors advance the concept that the polarization effects can be accounted for in a simple model based on quarks becoming polarized in the direct q-q scattering process and where, at a fundamental ...

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

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.

Quark Number Susceptibility with Finite Quark Mass in Holographic QCD
, 2011 We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D3/D7 model to calculate the quark number susceptibility at finite ...

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} $.

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 ...
