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.

RELATIVISTIC QUARK MODELS [PDF]

open access: yes, 2001
The application of relativistic constituent quark models to the evaluation of the electromagnetic properties of the nucleon and its resonances is addressed. The role of the pair creation process in the Feynmann triangle diagram is discussed and the importance both of choosing the light-front formalism and of using a Breit frame where the plus component

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.

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

open access: yesUniverse
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

Search for Possible Stable Structures in the Tccq¯s¯ System

open access: yesAtoms
Inspired by the well-known experimental connections between X(3872), Zcs(4220), and Y(4620), we systematically study the recently reported strange partner of Tcc, the 1+ccq¯s¯ system, and its orbital excitation state 1−ccq¯s¯.

Properties of color-flavor locked matter in a quasiparticle model

open access: yesEuropean 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

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.

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 ...
