Gluon condensates and effective gluon mass
SciPost 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.

Discovery of the bound state of three gluons - odderon [PDF]
Ядерна фізика та енергетика, 2021 The TOTEM collaboration at the Large Hadron Collider, together with the D0 collaboration at the Tevatron collider at Fermilab, have announced the discovery of the odderon – a bound state of three gluons that was predicted about 50 years ago.

Position-space gluon propagator from quenched lattice QCD [PDF]
EPJ Web of Conferences, 2022 We report novel lattice QCD results for the position-space gluon propagator in Landau gauge from quenched simulations. Using standard Wilson action, we computed gluon propagator in position space with a detailed treatment of hypercubic errors.

Baryon breakdown in black hole
Frontiers in Physics, 2022 According to relativity theory, a black hole is a distinct region in spacetime; according to astronomical observations, it is a celestial body transforming matter into high-energy jets.

Neutron star characteristics from the neutron structure
Frontiers in Physics, 2023 We draw insight into the neutron star structure and characteristics from the neutron structure. The eigenvectors of the special unitary group, SU(3), describing baryons, imply that neutron quarks reside on three faces of a tetrahedron.

Cross sections for gluon + gluon → heavy quarkonium + gluon [PDF]
Physics Letters B, 1987 Abstract Using the helicity amplitude formalism, we derive simple cross section formulae for the production of heavy quarkonia through the process g+g → ( 2S+1 L J )+ g when L = S or P. Within the framework of perturbative QCD, these subprocesses are important for the hadroproduction of heavy quarkonia.

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