Measurement of double-parton scattering in inclusive production of four jets with low transverse momentum in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
A measurement of inclusive four-jet production in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The transverse momenta of jets within |η| < 4.7 are required to exceed 35, 30, 25, and 20 GeV for the first-, second-, third ...

Parton Correlations in Double Parton Scattering [PDF]

open access: yes, 2018
Double parton scattering events are directly sensitive to the correlations between two partons inside a proton and can answer fundamental questions on the connections between the proton constituents. In this chapter, the different types of possible correlations, our present knowledge of them, and the processes where they are likely to be important, are

Two-loop splitting in double parton distributions: the colour non-singlet case

open access: yesJournal of High Energy Physics, 2021
At small inter-parton distances, double parton distributions receive their dominant contribution from the splitting of a single parton. We compute this mechanism at next-to-leading order in perturbation theory for all colour configurations of the ...

Production of three isolated photons in the high-energy factorization approach

open access: yesSciPost Physics Proceedings, 2022
We study large-$p_T$ three-photon production at the LHC at the center-of-mass energy $\sqrt{s}=8$ TeV. We use the LO approximation of the parton Reggeization approach consistently merged with the real NLO corrections.

Soft radiation in parton-parton scattering

open access: yesNuclear Physics B, 1987
Abstract We investigate the pattern of soft gluon radiation associated with parton-parton scattering by explicit evaluation of the 2 → 3 scattering processes in the soft limit. After azimuthal averaging, the results provide the initial conditions for an angular-ordering approximation to coherent multiple soft gluon emission, which may be incorporated

ρ meson GPDs and IPDs with a light-front constituent quark model [PDF]

open access: yesEPJ Web of Conferences, 2019
We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter

PARTON DISTRIBUTIONS [PDF]

open access: yesInternational Journal of Modern Physics A, 2004
I discuss our current understanding of parton distributions. I begin with the underlying theoretical framework, and the way in which different data sets constrain different partons, highlighting recent developments. The methods of examining the uncertainties on the distributions and those physical quantities dependent on them is analyzed.
