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.

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.

Two-Photon Exclusive Processes in QCD [PDF]

open access: yes, 2000
Exclusive two-photon reactions such as Compton scattering at large angles, deeply virtual Compton scattering, and hadron production in photon-photon collisions provide important tests of QCD at the amplitude level, particularly as measures of hadron ...

Sudakov effects in hadron-hadron elastic scattering

open access: yesPhysics Letters B, 1989
Abstract We exhibit the asymptotic amplitudes for meson-meson and baryon-baryon elastic scattering at high energy and fixed angle. These amplitudes include color-related phases. We outline how they may be derived by the summation of Sudakov logarithms associated with Landshoff-scattering subprocesses.

Soft high-energy hadron-hadron scattering

open access: yesPhysics Letters B, 1992
Abstract Total cross sections and the slope parameters of the elastic differential cross sections in hadron-hadron scattering are evaluated in a scheme based on a simple stochastic model for the physical vacuum.

Inclusive-photon production and its dependence on photon isolation in pp collisions at s $$ \sqrt{s} $$ = 13 TeV using 139 fb −1 of ATLAS data

open access: yesJournal of High Energy Physics, 2023
Measurements of differential cross sections are presented for inclusive isolated-photon production in pp collisions at a centre-of-mass energy of 13 TeV provided by the LHC and using 139 fb −1 of data recorded by the ATLAS experiment.

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

Inclusive and multiplicity dependent production of electrons from heavy-flavour hadron decays in pp and p-Pb collisions

open access: yesJournal of High Energy Physics, 2023
Measurements of the production of electrons from heavy-flavour hadron decays in pp collisions at s $$ \sqrt{s} $$ = 13 TeV at midrapidity with the ALICE detector are presented down to a transverse momentum (p T) of 0.2 GeV/c and up to p T = 35 GeV/c ...
