Graviton trispectrum from gluons
Journal of High Energy Physics, 2023 The tree-level wavefunction coefficient for four gravitons in de Sitter space was recently bootstrapped using the Cosmological Optical Theorem, flat space limit, and Manifestly Local Test [1].

Proton structure, its spin and tensor gluons
EPJ Web of Conferences, 2016 We assume that inside the hadrons there are additional partons - tensorgluons - which carry the same charges as the gluons, but have larger spin. That assumption leads to a possible contribution of polarised tensorgluon density to the spin of the nucleon.

On the Difference between the Radii of Gluons and Quarks
Physics, 2021 In this paper, in the scope of a non-extensive statistical model for the nucleon’s structure function, the volume of the gluons in the nucleons and the relations among the temperature, T, the parameter “q” of Tsallis statistics, and the scattering ...

Probing Sea Quarks and Gluons: The Electron-Ion Collider Project
EPJ Web of Conferences, 2014 The 21st century holds great promise for reaching a new era for unlocking the mysteries of the structure of the atomic nucleus and the nucleons inside it governed by the theory of strong interactions (QCD). In particular, much remains to be learned about

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.

Parton Distribution Functions in the CTEQ framework
Dera Natung Government College Research Journal, 2020 Parton distribution functions (PDFs) are important to study the structure of the proton and hence the dynamics of quarks and gluons inside it. We study some of the PDFs from global CTEQ (Coordinated Theoretical-Experimental project on QCD) analysis in a ...

Physical 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 ...

Diffraction and the gluon mass [PDF]
Physical Review D, 1993 We recently proposed a QCD-Pomeron described by the exchange of two non-perturbative gluons characterized by a dynamically generated gluon mass. It is here shown that data on elastic scattering, exclusive $ρ$ production in deep inelastic scattering and the $J/Ψ$-nucleon total cross-section can be successfully described in terms of a single gluon mass ...

Bose-Einstein Condensation from the QCD Boltzmann Equation
Particles, 2019 We present a novel numerical scheme to solve the QCD Boltzmann equation in the soft scattering approximation, for the quenched limit of QCD. Using this we can readily investigate the evolution of spatially homogeneous systems of gluons distributed ...
