Strong Effective Coupling, Meson Ground States, and Glueball within Analytic Confinement

open access: yesParticles, 2019
The phenomena of strong running coupling and hadron mass generating have been studied in the framework of a QCD-inspired relativistic model of quark-gluon interaction with infrared-confined propagators.

Recent results on top quark mass and properties and rare/anomalous top quarks interactions in CMS

open access: yesSciPost Physics Proceedings, 2022
The amount of data collected by the CMS experiment at the CERN LHC in the second data taking period provides the possibility to study absolute and differential cross sections of top quark interaction processes with high precision.

Sub-leading twist transverse momentum dependent parton distributions in the light-front quark-diquark model

open access: yesNuclear Physics B, 2023
In this study, the T-even sub-leading twist transverse momentum dependent distributions (TMDs) of proton in the light-front quark-diquark model (LFQDM) have been investigated. We have derived the overlap form of the light-front wave functions (LFWFs) for

Phase transition from hadronic matter to quark matter [PDF]

open access: yes, 2006
We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equation of state for nuclear matter, while the equation of state for color ...

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.

Quark matter and quark stars at finite temperature in Nambu–Jona-Lasinio model

open access: yesEuropean 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 ...

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 ...
