Gluon condensates and effective gluon mass

open access: yesSciPost Physics, 2022
Lattice simulations along with studies in continuum QCD indicate that non-perturbative quantum fluctuations lead to an infrared regularisation of the gluon propagator in covariant gauges in the form of an effective mass-like behaviour.

Gluon Theory; A model of the Oneness of Being [PDF]

open access: yesحکمت و فلسفه, 2016
There are true contradictions in Ibn ‘Arabi’s theory of the Oneness of Being. The most important one occurs in his explanation of the relation between Being and beings.

Four-point correlators of light-ray operators in CCFT

open access: yesJournal of High Energy Physics, 2022
We compute the four-point correlator of two gluon light-ray operators and two gluon primaries from the four-gluon celestial amplitude in (2, 2) signature spacetime.

Probing gluon number density with electron-dijet correlations at EIC

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We propose a novel way of studying the gluon number density (the so-called Weizsäcker–Williams gluon distribution) using the planned Electron Ion Collider.

Approximate four-loop QCD corrections to the Higgs-boson production cross section

open access: yesPhysics Letters B, 2020
We study the soft and collinear contributions to inclusive Higgs-boson production in gluon-gluon fusion at four loops. Using recent progress for the quark and gluon form factors and Mellin moments of splitting functions, we are able to complete the soft ...

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 ...

Several Effects Unexplained by QCD

open access: yesUniverse, 2018
Several new experimental discoveries in high energy proton interactions, yet unexplained by QCD, are discussed in the paper. The increase of the cross sections with increasing energy from ISR to LHC, the correlation between it and the behavior of the ...

Gluon mass generation without seagull divergences [PDF]

open access: yes, 2009
Dynamical gluon mass generation has been traditionally plagued with seagull divergences, and all regularization procedures proposed over the years yield finite but scheme-dependent gluon masses. In this work we show how such divergences can be eliminated

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

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.
