Lattice approach to high–energy hadron–hadron scattering [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2009
We discuss the non perturbative approach to the problem of high-energy hadron-hadron (dipole-dipole) scattering at low momentum transfer by means of numerical simulations in Lattice Gauge Theory.

Producing and detecting long-lived particles at different experiments at the LHC

open access: yesJournal of High Energy Physics, 2022
We propose a new strategy to look for long-lived particles (LLP) at the LHC. The LLPs are produced at one experiment, but its decay products are detected by a detector at another experiment.

Search for high-mass Wγ and Zγ resonances using hadronic W/Z boson decays from 139 fb −1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for high-mass charged and neutral bosons decaying to Wγ and Zγ final states is presented in this paper. The analysis uses a data sample of s $$ \sqrt{s} $$ = 13 TeV proton-proton collisions with an integrated luminosity of 139 fb −1 collected by

Prompt and non-prompt J/ψ production cross sections at midrapidity in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 5.02 and 13 TeV

open access: yesJournal of High Energy Physics, 2022
The production of J/ψ is measured at midrapidity (|y| < 0.9) in proton-proton collisions at s $$ \sqrt{s} $$ = 5.02 and 13 TeV, through the dielectron decay channel, using the ALICE detector at the Large Hadron Collider.

Search for a new heavy scalar particle decaying into a Higgs boson and a new scalar singlet in final states with one or two light leptons and a pair of τ-leptons with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for a new heavy scalar particle X decaying into a Standard Model (SM) Higgs boson and a new singlet scalar particle S is presented. The search uses a proton-proton (pp) collision data sample with an integrated luminosity of 140 fb −1 recorded at

Polarization Effects In Hadron-Hadron Scatterings

open access: yesCumhuriyet Science Journal, 2018
In the case of diffraction scattering of hadrons by hadrons, a nonzero polarization of the scattered particles arises, which is related to the logarithmic derivative of the differential scattering cross section. Polarization changes sign in those reactions whose angular distributions contain the second diffraction maximum.

Hadron-hadron scattering at high energies [PDF]

open access: yesBrazilian Journal of Physics, 2000
We review the role of the QCD vacuum structure in the determination of the properties of states and processes occurring in the confinement regime of QCD. The vacuum correlation model of non-perturbative QCD is mentioned as a bridge between the fundamental theory and the description of the experiments.

Electromagnetic corrections to hadron-hadron scattering

open access: yesNuclear Physics B, 1974
Abstract We use S -matrix methods to determine the electromagnetic corrections to relativistic hadron scattering. The infrared divergences associated with soft photon emission and with the Coulomb interaction are removed to give a finite scattering amplitude which obeys crossing and has the usual analytic structure. An approximate calculation of the

Modelling and computational improvements to the simulation of single vector-boson plus jet processes for the ATLAS experiment

open access: yesJournal of High Energy Physics, 2022
This paper presents updated Monte Carlo configurations used to model the production of single electroweak vector bosons (W, Z/γ ∗) in association with jets in proton-proton collisions for the ATLAS experiment at the Large Hadron Collider.

Measurement of Higgs boson decay into b-quarks in associated production with a top-quark pair in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2022
The associated production of a Higgs boson and a top-quark pair is measured in events characterised by the presence of one or two electrons or muons. The Higgs boson decay into a b-quark pair is used.
