Charge symmetry violation in the parton distributions of the nucleon [PDF]

, 2000
We point out that charge symmetry violation in both the valence and sea quark distributions of the nucleon has a non-perturbative source. We calculate this non-perturbative charge symmetry violation using the meson cloud model, which has earlier been ...

Quark-gluon double parton distributions in the light-front dressed quark model [PDF]

, 2016
We study parton distributions for two partons, a quark and a gluon, in the light-front dressed quark model, with a focus on the correlations between the two partons.

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.

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} $.

Search for doubly-heavy dibaryons in a quark model [PDF]

, 2016
We study the stability of hexaquark systems containing two heavy quarks and four light quarks within a simple quark model. No bound or metastable state is found.

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

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 ...

The Effective Baryon–Baryon Potential with Configuration Mixing in Quark Models

Universe
The 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.
