A covariant description of the interactions of axion-like particles and hadrons

open access: yesJournal of High Energy Physics
We present a covariant framework for analyzing the interactions and decay rates of axion-like particles (ALPs) that couple to both gluons and quarks. We identify combinations of couplings that are invariant under quark-field redefinitions, and use them ...

Approximate Hamiltonian for baryons in heavy-flavor QCD

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Aiming at relativistic description of gluons in hadrons, the renormalization group procedure for effective particles (RGPEP) is applied to baryons in QCD of heavy quarks.

Covariant kinetic theory and transport coefficients for Gribov plasma

open access: yesPhysics Letters B, 2020
Gribov quantization is a method to improve the infrared dynamics of Yang-Mills theory. We study the thermodynamics and transport properties of a plasma consisting of gluons whose propagator is improved by the Gribov prescription.

A look at hadronization via high multiplicity [PDF]

open access: yesEPJ Web of Conferences, 2019
Multiparticle production is studied experimentally and theoretically in QCD that describes interactions in the language of quarks and gluons. In the experiment the real hadrons are registered.

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Light-cone singularities and transverse-momentum-dependent factorization at twist-3

open access: yesPhysics Letters B, 2017
We study transverse-momentum-dependent factorization at twist-3 for Drell–Yan processes. The factorization can be derived straightforwardly at leading order of αs.

Coulomb gluons will generally destroy coherence

open access: yesJournal of High Energy Physics, 2021
Coherence violation is an interesting and counter-intuitive phenomenon in QCD. We discuss the circumstances under which violation occurs in observables sensitive to soft radiation and arrive at the conclusion that almost all such observables at hadron ...

Charmonium suppression by gluon bremsstrahlung in p-A and A-B collisions

open access: yes, 1999
Prompt gluons are an additional source for charmonium suppression in nuclear collisions, in particular for nucleus-nucleus collisions. These gluons are radiated as bremsstrahlung in N-N collisions and interact inelastically with the charmonium states ...

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Color Confinement and Massive Gluons

open access: yes, 2005
Color confinement is one of the central issues in QCD so that there are various interpretations of this feature. In this paper we have adopted the interpretation that colored particles are not subject to observation just because colored states are ...
