Infrared analysis of propagators and vertices of Yang--Mills theory in Landau and Coulomb gauge [PDF]

open access: yes, 2006
The infrared behaviour of gluon and ghost propagators, ghost-gluon vertex and three-gluon vertex is investigated for both the covariant Landau and the non-covariant Coulomb gauge.

One-loop central-emission vertex for two gluons in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory

open access: yesJournal of High Energy Physics, 2022
A necessary ingredient for extending the BFKL equation to next-to-next-to-leading logarithmic (NNLL) accuracy is the one-loop central emission vertex (CEV) for two gluons which are not strongly ordered in rapidity. Here we consider the one-loop six-gluon

The field strength correlator from QCD sum rules [PDF]

open access: yes, 1999
The gauge invariant two-point correlator for the gluon field strength tensor in analysed by means of the QCD sum rule method. To this end, we make use of a relation of this correlator to a two-point function for a quark-gluon hybrid in the limit of the ...

Color Randomization of Fast Gluon-Gluon Pairs in the Quark-Gluon Plasma [PDF]

open access: yesJournal of Experimental and Theoretical Physics, 2019
We study the color randomization of two-gluon states produced after splitting of a primary fast gluon in the quark-gluon plasma. We find that for the LHC conditions the color randomization of the $gg$ pairs is rather slow. At jet energies $E=100$ and $500$ GeV, for typical jet path length in the plasma in central Pb+Pb collisions, the $SU(3)$-multiplet

Gluon fusion contribution to VHj production at hadron colliders

open access: yesPhysics Letters B, 2015
We study the associated production of an electroweak vector boson and the Higgs boson with a jet via gluon–gluon fusion. At the leading order, these processes occur at one-loop level.

Splitting the gluon? [PDF]

open access: yesPhysical Review D, 2005
In the strongly correlated environment of high-temperature cuprate superconductors, the spin and charge degrees of freedom of an electron seem to separate from each other. A similar phenomenon may be present in the strong coupling phase of Yang-Mills theories, where a separation between the color charge and the spin of a gluon could play a role in a ...

Topological ?vector gluons? [PDF]

open access: yesZeitschrift f�r Physik C Particles and Fields, 1982
A topological representation for individual quark chirality is proposed which eliminates spin lines from the classical surface and provides “chiral entropy” through patch-boundary lines that correspond to chirality reversal. The effect on quark spin makes it appropriate to describe such a patch-boundary line as a “topological vector gluon”.

Numerical analysis of the unintegrated double gluon distribution

open access: yesJournal 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

open access: yesPhysics 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 ...

Gluon-gluon fusion production mode.

open access: yes, 2013
This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. This report follows the first working group report
