Wigner distributions for gluons in a light-front dressed quark model [PDF]

open access: yes, 2015
We present a calculation of Wigner distributions for gluons in light-front dressed quark model. We calculate the kinetic and canonical gluon orbital angular momentum and spin-orbit correlation of the gluons in this model.

Linearized Boltzmann-Langevin model for heavy quark transport in hot and dense QCD matter [PDF]

open access: yesPhysical Review C, 2018
In relativistic heavy-ion collisions, the production of heavy quarks at large transverse momenta is strongly suppressed compared to proton-proton collisions.

Thermoelectric transport coefficients of quark matter

open access: yesEuropean 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.

Dibaryons in a constituent quark model [PDF]

open access: yes, 2015
We investigate the properties of dibaryons containing u and d quarks in the constituent quark model. In constructing the ground state wave function, we choose the spatial part to be fully symmetric and the remaining color, isospin and spin part to be ...

Study of heavy quark conserving weak decays in the quark model

open access: yesPhysics 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 ...

Light-front holographic ρ-meson distributions in the momentum space

open access: yesJournal 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.

Measurement of the Top Quark Mass in the Dilepton Final State using the Matrix Element Method [PDF]

open access: yes, 2008
The top quark, discovered in 1995 by the CDF and D0 experiments at the Fermilab Tevatron Collider, is the heaviest known fundamental particle. The precise knowledge of its mass yields important constraints on the mass of the yet-unobserved Higgs boson ...

New signals for vector-like down-type quark in U(1) of $$E_6$$ E6

open access: yesEuropean 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.

The dual quark models

open access: yes, 2012
We briefly recall the historical environment around our 1971 and 1975 constructions of current-algebraic internal symmetry on the open string. These constructions included the introduction of world sheet fermions, the independent discovery of affine Lie algebra in physics (level one of affine su(3)), the first examples of the affine-Sugawara and coset ...
