European Physical Journal C: Particles and Fields, 2018 We discuss the high energy scattering of hadrons with the multi-Regge kinematics. The effective 2D model for the interaction between the produced hard gluons appears as a result of the dimensional reduction, which is similar to the dimensional reduction $

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

Higher-derivative relations between scalars and gluons
, 2023 We extend the covariant color-kinematics duality introduced by Cheung and Mangan to effective field theories. We focus in particular on relations between the effective field theories of gluons only and of gluons coupled to bi-adjoint scalars.

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

Gluon decay as a mechanism for strangeness production in a quark-gluon plasma [PDF]
Physical Review C, 1995 A calculation of thermal gluon decay shows that this process contributes significantly to strangeness production in a quark-gluon plasma. Our analysis does not support recent claims that this is the dominant process. In our calculations we take into account the resummed form of the transverse and longitudinal parts of the gluon propagator following the

Wigner distributions for gluons
European 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
Physics 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.

Three-Loop Gluon Scattering in QCD and the Gluon Regge Trajectory
Physical Review Letters, 2022 We compute the three-loop helicity amplitudes for the scattering of four gluons in QCD. We employ projectors in the 't Hooft-Veltman scheme and construct the amplitudes from a minimal set of physical building blocks, which allows us to keep the computational complexity under control.

A New Method for Calculating the Energies Associated with Particle Reactions
Reports in Advances of Physical SciencesA 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.

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