Quaternion Algebra on 4D Superfluid Quantum Space-Time: Can Dark Matter Be a Manifestation of the Superfluid Ether?

open access: yesUniverse, 2021
Quaternions are a natural framework of 4D space-time, where the unit element relates to time, and three others relate to 3D space. We define a quaternion set of differential torsion operators (shifts with rotations) that act to the energy-momentum tensor

Bulk strong matter: the trinity

open access: yesAdvances in Physics: X, 2023
Our world is wonderful because of the normal but negligibly small baryonic part (i.e. atoms) although unknown dark matter and dark energy dominate the Universe.

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.

Quantum oscillons may be long-lived

open access: yesJournal of High Energy Physics, 2023
Hertzberg has constructed a quantum oscillon that decays into pairs of relativistic mesons with a power much greater than the radiation from classical oscillon decay.

QLBT: a linear Boltzmann transport model for heavy quarks in a quark-gluon plasma of quasi-particles

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We develop a new heavy quark transport model, QLBT, to simulate the dynamical propagation of heavy quarks inside the quark-gluon plasma (QGP) created in relativistic heavy-ion collisions.

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

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.

The colour of quarks [PDF]

open access: yesPhysics Letters B, 1996
It is shown that colour can only be defined on gauge invariant states. Since the ability to associate colour with constituent quarks is an integral part of the constituent quark model, this means that, if we want to extract constituent quarks from QCD, we need to dress Lagrangian quarks with gluons so that the result is gauge invariant.
