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 ...

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.

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.

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.

About the vacuum structure in QCD and hadron-hadron scattering [PDF]

open access: yesZeitschrift für Physik C Particles and Fields, 1985
We comment on an unconventional factorization scheme which has been recently proposed by Nachtmann and Reiter. These authors propose to take into account the influence of the vacuum structure of QCD by including a correlation in spin and colour for the partons that initiate a hard scattering process.

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

The vacuum structure in QCD and hadron-hadron scattering

open access: yesZeitschrift f�r Physik C: Particles and Fields, 1984
Standard ideas on the structure of the vacuum in QCD suggest it to be full of fluctuating color fields. We investigate the possible influence of the chromomagnetic vacuum fields on high energy hadron-hadron reactions. We suggest that high energy quarks traversing these fields will produce soft gluon and photon radiation analogous to synchrotron ...
