Quark propagation in a quark–gluon plasma with gluon condensate [PDF]

open access: yesPhysics Letters B, 1999
We present a calculation of the thermal quark propagator taking the gluon condensate above the critical temperature into account. The quark dispersion relation following from this propagator, describing two massive modes, is discussed.

One-loop light-cone QCD, effective action for reggeized gluons and QCD RFT calculus

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
The effective action for reggeized gluons is based on the gluodynamic Yang–Mills Lagrangian with external current for longitudinal gluons added, see Lipatov (Nucl Phys B 452:369, 1995; Phys Rep 286:131, 1997; Subnucl Ser 49:131, 2013; Int J Mod Phys Conf

A New Method for Calculating the Energies Associated with Particle Reactions

open access: yesReports in Advances of Physical Sciences
A new method in which the energy and mass of elementary particles can be calculated is presented. Gluon-gluon interactions within a single elementary particle are considered, and the number of possible interactions per particle is determined.

Wigner distributions for gluons

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We investigate the gluon Wigner distributions for unpolarized, longitudinally polarized and transversely polarized target state. Instead of a nucleon, we take the target state to be a quark dressed with a gluon at one loop and investigate the gluon ...

Deep-learning quasi-particle masses from QCD equation of state

open access: yesPhysics Letters B, 2023
The interactions of quarks and gluons are strong in the non-perturbative regime. The equation of state (EoS) of a strongly-interacting quantum chromodynamics (QCD) medium can only be studied using the first-principle lattice QCD calculations.

Gluon-gluon fusion at HERA

open access: yesPhysics Letters B, 1991
Abstract We calculate corrections to the electroproduction cross section of J/ψ at HERA energies arising from gluons in the photon interacting with gluons in the proton. These turn out to be sizable and may be isolated by suitable phase space cuts. Implications for the extraction of the gluon density of the proton at HERA are also discussed.

How to measure the linear polarization of gluons in unpolarized proton using the heavy-quark pair production [PDF]

open access: yesEPJ Web of Conferences, 2019
In recent papers [1, 2], two new ways have been proposed to probe the linear polarization of gluons in unpolarized proton: using the azimuthal asymmetries and Callan-Gross ratio in heavy-quark pair leptoproduction, lN → l′QQ̅X.

Multimodal Fragmentation of Hidden‐Heavy Scalar Tetraquarks With HF‐NRevo

open access: yesAnnalen der Physik, Volume 538, Issue 10, October 2026.
A state‐driven multimodal framework is introduced for hidden‐heavy scalar tetraquark fragmentation. Distinct microscopic production mechanisms are consistently related to different internal hadronic configurations while theoretical uncertainties are systematically quantified.
