Quark-Meson Coupling Model with Short-Range Quark-Quark Interactions [PDF]

open access: yesProgress of Theoretical Physics, 2001
Short-range quark-quark correlations are introduced into the quark-meson coupling (QMC) model phenomenologically. We study the effect of the correlations on the structure of the nucleon in dense nuclear matter. With the addition of correlations, the saturation curve for symmetric nuclear matter is much improved at high density.

Quark mass density- and temperature- dependent model for bulk strange quark matter [PDF]

open access: yes, 2002
It is shown that the quark mass density-dependent model can not be used to explain the process of the quark deconfinement phase transition because the quark confinement is permanent in this model.

Off-equilibrium non-Gaussian fluctuations near the QCD critical point: an effective field theory perspective

open access: yesJournal of High Energy Physics, 2022
The non-Gaussian fluctuations of baryon density are sensitive to the presence of the conjectured QCD critical point. Their observational consequences are crucial for the ongoing experimental search for this critical point through the beam energy scan ...

Scotogenic Dirac neutrino mass models embedded with leptoquarks: one pathway to address the flavor anomalies and the neutrino masses together

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
If the leptoquarks proposed to account for the intriguing anomalies observed in the semileptonic B-meson decays, $$R_{D^{(*)}}$$ R D ( ∗ ) and $$R_{K^{(*)}}$$ R K ( ∗ ) , as well as in the anomalous magnetic moment of the muon, $$(g-2)_\mu $$ ( g - 2 ) μ

Runaway quarks [PDF]

open access: yesPhysical Review D, 1995
When heavy nuclei collide, a quark-gluon plasma is formed. The plasma is subject to strong electric field due to the charge of the colliding nuclei. The electric field can influence the behavior of the quark-gluon plasma. In particular, we might observe an increased number of quarks moving in the direction of that field, as we do in the standard ...

Spectral function of quarks in quark matter [PDF]

open access: yesPhysical Review C, 2003
We investigate the spectral function of light quarks in infinite quark matter using a simple, albeit self-consistent model. The interactions between the quarks are described by the SU(2) Nambu--Jona-Lasinio model. Currently mean field effects are neglected and all calculations are performed in the chirally restored phase at zero temperature.

Quark motional effects on the interquark potential in baryons [PDF]

open access: yes, 2008
We study the heavy-heavy-light quark ($QQq$) system in a non-relativistic potential model, and investigate the quark motional effect on the inter-two-quark potential in baryons.

Thermodynamics and energy loss in D dimensions from holographic QCD model

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We consider the holographic QCD model with a planar horizon in the D dimensions with different consistent metric solutions. We investigate the black hole thermodynamics, phase diagram and equations of state (EoS) in different dimensions.

Top quark decays into heavy quark mesons [PDF]

open access: yesPhysical Review D, 1996
For top quark decays into heavy quark mesons $ $ and $\bar{B}_c^*$ , a complete calculation to the leading order both in QCD coupling constant $ _s$ and in $v$, the typical velocity of the heavy quarks inside the mesons, is performed. Relatons between the top quark mass and the decay branching ratios are studied.

Covariant and heavy quark symmetric quark models [PDF]

open access: yesPhysical Review D, 1994
There exist relativistic quark models (potential or MIT-bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. Covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions.Proton form factor and M1 transitions in quarkonia are ...
