Search for a light charged Higgs boson in t → H ± b decays, with H ± → cb, in the lepton+jets final state 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 a charged Higgs boson, H ± , produced in top-quark decays, t → H ± b, is presented. The search targets H ± decays into a bottom and a charm quark, H ± → cb. The analysis focuses on a selection enriched in top-quark pair production, where one

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

A Parton-Hadron Cascade Approach in High-energy Nuclear Collisions [PDF]

open access: yes, 1998
A parton-hadron cascade model which is the extension of hadronic cascade model incorporating hard partonic scattering based on HIJING is presented to describe the space-time evolution of parton/hadron system produced by ultra-relativistic nuclear ...

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.

Diffraction at HERA and the Confinement Problem [PDF]

open access: yes, 2000
We discuss HERA data on the high energy behavior of the total gamma*p cross section and on diffraction in deep inelastic scattering. We outline their novelty in comparison with diffraction in high energy hadron hadron scattering.

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.

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 ...

Factorization and Non-factorization in Diffractive Hard Scattering [PDF]

open access: yes, 1997
Factorization, in the sense defined for inclusive hard scattering, is discussed for diffractive hard scattering. A factorization theorem similar to its inclusive counterpart is presented for diffractive DIS. For hadron-hadron diffractive hard scattering,

Gravitation interaction with extra dimension and periodic structure of the hadron scattering amplitude

open access: yes, 2011
The behavior of the hadron scattering amplitude determined by the gravitation interaction of hadron at high energies with impact of the KK-modes in d-brane models of gravity is examined. The possible periodic structure of the scattering amplitude and its
