Measurement of χ c1(3872) production in proton-proton collisions at s $$ \sqrt{s} $$ = 8 and 13 TeV

open access: yesJournal of High Energy Physics, 2022
The production cross-section of the χ c1(3872) state relative to the ψ(2S) meson is measured using proton-proton collision data collected with the LHCb experiment at centre-of-mass energies of s $$ \sqrt{s} $$ = 8 and 13 TeV, corresponding to integrated ...

Colour distribution in hadron-hadron scattering [PDF]

open access: yesPhysics Letters B, 1979
Abstract In high p t quark-quark scattering a simple picture emerges for the colour distribution in the final state: the scattered quark of one of the incident hadrons forms a colour singlet with the spectators of the other hadron, i.e., the four fast coloured objects form two singlets. We assume that the decay of each colour single pair - apart

Searches for lepton-flavour-violating decays of the Higgs boson into eτ and μτ in s $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
This paper presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ, performed using data collected with the ATLAS detector at the LHC.

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.

Parton Models and Deep Hadron‐Hadron Scattering [PDF]

open access: yesAIP Conference Proceedings, 1973
We review the recent applications of various parton models, to the problem of hadron‐hadron scattering at large momentum transfers. Models which allow direct parton‐parton interaction as well as those that do not are considered. Predictions for the structure of hadronic final states (whether or not transverse jets exist), associated multiplities, and ...

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

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.
