On relevance of triple gluon fusion in $J/\psi$ hadroproduction [PDF]
, 2015 A contribution to $J/\psi$ hadroproduction is analyzed in which the meson production is mediated by three-gluon partonic state, with two gluons coming from the target and one gluon from the projectile.

Numerical analysis of the unintegrated double gluon distribution
Journal of High Energy Physics, 2018 We present detailed numerical analysis of the unintegrated double gluon distribution which includes the dependence on the transverse momenta of partons. The unintegrated double gluon distribution was obtained following the Kimber-Martin-Ryskin method as ...

Schwinger mechanism for gluons from lattice QCD
Physics Letters B, 2023 Continuum and lattice analyses have revealed the existence of a mass-scale in the gluon two-point Schwinger function. It has long been conjectured that this expresses the action of a Schwinger mechanism for gauge boson mass generation in quantum ...

What the Infrared Behaviour of QCD Vertex Functions in Landau gauge can tell us about Confinement [PDF]
, 2007 The infrared behaviour of Landau gauge QCD vertex functions is investigated employing a skeleton expansion of the Dyson-Schwinger and Renormalization Group equations.

The gluon structure of hadrons and nuclei from lattice QCD
EPJ Web of Conferences, 2018 I discuss recent lattice QCD studies of the gluon structure of hadrons and light nuclei. After very briefly highlighting new determinations of the gluon contributions to the nucleon’s momentum and spin, presented by several collaborations over the last ...

The quark-gluon vertex and the QCD infrared dynamics
European Physical Journal C: Particles and Fields, 2019 The Dyson–Schwinger quark equation is solved for the quark-gluon vertex using the most recent lattice data available in the Landau gauge for the quark, gluon and ghost propagators, the full set of longitudinal tensor structures in the Ball-Chiu vertex ...

The small $x$ behavior of the gluon structure function from total cross sections [PDF]
, 2007 Within a QCD-based eikonal model with a dynamical infrared gluon mass scale we discuss how the small $x$ behavior of the gluon distribution function at moderate $Q^{2}$ is directly related to the rise of total hadronic cross sections.

Critical coupling for dynamical chiral-symmetry breaking with an infrared finite gluon propagator [PDF]
, 1996 We compute the critical coupling constant for the dynamical chiral-symmetry breaking in a model of quantum chromodynamics, solving numerically the quark self-energy using infrared finite gluon propagators found as solutions of the Schwinger-Dyson ...

Early thermalization of quark-gluon matter with the elastic scattering of ggq and ggqbar
, 2013 Elastic gluon-gluon-quark (gluon-gluon-antiquark) scattering is studied in perturbative QCD with 123 Feynman diagrams at the tree level. Individually squared amplitudes and interference terms of the Feynman diagrams are derived.

The gluon condensation in hadron collisions
Nuclear Physics B, 2022 Gluons may converge to a stable state at a critical momentum in hadrons. This gluon condensation is predicted by a nonlinear QCD evolution equation. We review the understanding of the gluon condensation and present a clear physical picture that produces ...
