Parton Distribution Functions in the CTEQ framework

open access: yesDera 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 ...

Graviton trispectrum from gluons

open access: yesJournal 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].

Bose-Einstein Condensation from the QCD Boltzmann Equation

open access: yesParticles, 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 ...

Studying mass generation for gluons

open access: yesSciPost Physics Proceedings, 2022
In covariant gauges, the gluonic mass gap in Yang-Mills theory manifests itself in the basic observation that the massless pole in the perturbative gluon propagator disappears in nonperturbative calculations, but the origin of this behavior is not yet ...

Low-x improved TMD approach to the lepto- and hadroproduction of a heavy-quark pair

open access: yesJournal of High Energy Physics, 2021
We study the lepto- and hadroproduction of a heavy-quark pair in the ITMD factorization framework for dilute-dense collisions. Due to the presence of a nonzero quark mass and/or nonzero photon virtuality, new contributions appear compared to the cases of

On the Difference between the Radii of Gluons and Quarks

open access: yesPhysics, 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 ...

On broad Kaluza-Klein gluons

open access: yesJournal of High Energy Physics, 2021
In theories with a warped extra dimension, composite fermions, as e.g. the right-handed top quark, can be very strongly coupled to Kaluza-Klein (KK) fields.

Abelian Decomposition and Monopole Condensation in QCD

open access: yesEPJ Web of Conferences, 2018
We demonstrate the monopole condensation in QCD using the Abelian decomposition. The Abelian decomposition decomposes the gluons to the color neutral binding gluons (the neurons and the monopoles) and the colored valence gluons (the chromons), and shows ...

Triple (and quadruple) soft-gluon radiation in QCD hard scattering

open access: yesJournal of High Energy Physics, 2020
We consider the radiation of three soft gluons in a generic process for multi- parton hard scattering in QCD. In the soft limit the corresponding scattering amplitude has a singular behaviour that is factorized and controlled by a colorful soft current ...

Gluon TMD studies at EIC

open access: yesEPJ Web of Conferences, 2016
A high-energy Electron-Ion Collider (EIC) would offer a most promising tool to study in detail the transverse momentum distributions of gluons inside hadrons.
