Iterating QCD scattering amplitudes in the high-energy limit

Journal of High Energy Physics, 2018
We analyse the high-energy limit of the gluon-gluon scattering amplitude in QCD, and display an intriguing relation between the finite parts of the one-loop gluon impact factor and the finite parts of the two-loop Regge trajectory.

QCD evolution based evidence for the onset of gluon saturation in exclusive photo-production of vector mesons

Physics Letters B, 2019
We investigate photo-production of vector mesons J/Ψ and ϒ measured both at HERA and LHC, using 2 particular fits of inclusive unintegrated gluon distributions, based on non-linear Balitsky-Kovchegov evolution (Kutak-Sapeta gluon; KS) and next-to-leading

The Weighted GMD Model for multiplicity distributions

EPJ Web of Conferences, 2016
A new distribution, the Weighted GMD (WGMD) is obtained from the Generalised Multiplicity Distribution (GMD), describing charged-particle multiplicity distributions as the hadronisation products of quark and gluon branching with fluctuations in the ...

MHV gluon scattering amplitudes from celestial current algebras

Journal of High Energy Physics, 2021
We show that the Mellin transform of an n-point tree level MHV gluon scattering amplitude, also known as the celestial amplitude in pure Yang-Mills theory, satisfies a system of (n−2) linear first order partial differential equations corresponding to (n ...

T-odd transverse momentum dependent gluon fragmentation functions in a spectator model

Physics Letters B
We present a model calculation of the T-odd transverse momentum dependent (TMD) gluon fragmentation functions for a spin-1/2 hadron. Our model is based on the postulation that a time-like off-shell gluon can fragment into a hadron and a single spectator ...

Classification of four-point local gluon S-matrices

Journal of High Energy Physics, 2021
In this paper, we classify four-point local gluon S-matrices in arbitrary dimensions. This is along the same lines as [1] where four-point local photon S-matrices and graviton S-matrices were classified.

Zero-momentum correlator in SU(2) Landau gauge gluodynamics under various boundary conditions

EPJ Web of Conferences, 2017
We make new simulations of S U(2) zero spatial momentum (ZM) gluon correlator in Landau gauge gluodynamics paying special attention to possible lattice artefacts and Gribov copy effect.

Extraction of gluon distributions from structure functions at small x in holographic QCD

Physics Letters B, 2020
We investigate the nucleon and pion gluon distribution functions in the framework of holographic QCD, focusing on the small Bjorken x region. Based on an approximate relation, the gluon distributions are extracted from structure functions of the ...

Predictions for charged-hadron production in p-O collisions at LHC energies

Physics Letters B
We present predictions for centrality-dependent charged-hadron production in p-O collisions at top LHC energies based on a nonequilibrium-statistical relativistic diffusion model.
