Fixed-Angle Elastic Hadron Scattering [PDF]

open access: yes, 1999
The scattering amplitude in the dual model with Mandelstam analyticity and trajectory $\alpha (s)=\alpha_{0}-\gamma \ln [ (1+\beta \sqrt{s_{0} -s})/(1+ \beta \sqrt{s_{0}})]$ is studied in the limit $s,|t|\to \infty, s/t=const.$ By using the saddle point ...

Measurements of Zγ+jets differential cross sections in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
Differential cross-section measurements of Zγ production in association with hadronic jets are presented, using the full 139 fb −1 dataset of s $$ \sqrt{s} $$ = 13 TeV proton–proton collisions collected by the ATLAS detector during Run 2 of the LHC ...

Hadron-hadron scattering at very low energies

open access: yesInternational Journal of Modern Physics: Conference Series, 2015
In this paper we study the contribution of the incoming hadrons’ polarization to the differential cross section of the hadron scattering at the ultra low energy limit. It is shown that their polarization does not have significant effect on the differential cross section of such scattering. The polarization of the outgoing hadrons is also analyzed.

Search for a new scalar resonance in flavour-changing neutral-current top-quark decays t → qX (q = u, c), with X → b b ¯ $$ b\overline{b} $$ , in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for flavour-changing neutral-current decays of a top quark into an up-type quark (either up or charm) and a light scalar particle X decaying into a bottom anti-bottom quark pair is presented. The search focuses on top-quark pair production where

Factorization for short distance hadron-hadron scattering

open access: yesNuclear Physics B, 1985
Abstract We show that factorization holds at leading twist in the Drell-Yan cross section dσ/dQ2dy and related inclusive hadron-hadron cross sections. We review the heuristic arguments for factorization, as well as the difficulties which must be overcome in a proof.

The Color Glass Condensate

open access: yes, 2010
We provide a broad overview of the theoretical status and phenomenological applications of the Color Glass Condensate effective field theory describing universal properties of saturated gluons in hadron wavefunctions that are extracted from deeply ...

A New Fracture Function Approach to QCD Initial State Radiation [PDF]

open access: yes, 2007
Ordinary fracture functions, describing hadrons production in the deep inelastic scattering target fragmentation region, are generalized to account for the production of hadrons in arbitrary number, thus offering a renewed framework for dealing with QCD ...

GLUON BREMSTRAHLUNG EFFECTS IN LARGE p HADRON-HADRON SCATTERING [PDF]

open access: yesAIP Conference Proceedings, 1982
We consider effects of parton (primarily gluon) bremstrahlung in the initial and final states of high transverse momentum hadron‐hadron scattering. Monte Carlo calculations based on conventional QCD parton branching and scattering processes are presented. The calculations are carried only to the parton level in the final state.

Isospin quantum distances in hadron-hadron scattering

open access: yesPhysics Letters B, 1996
Abstract In this paper, the quantum distances between two isospin channels, in the Hilbert space of the hadron-hadron scattering amplitudes, are introduced. These isospin quantum distances, as well as their isospin bounds, are expressed in terms of the channel cross sections and polarisation parameters.
