The Optical Potential on the Lattice [PDF]

open access: yes, 2016
The extraction of hadron-hadron scattering parameters from lattice data by using the L\"uscher approach becomes increasingly complicated in the presence of inelastic channels.

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.

Uncovering the Scaling Laws of Hard Exclusive Hadronic Processes in a Comprehensive Endpoint Model [PDF]

open access: yes, 2014
We show that an endpoint overlap model can explain the scaling laws observed in exclusive hadronic reactions at large momentum transfer. The model assumes one of the valence quarks carries most of the hadron momentum.

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.

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 ...

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.

Like-Sign W Boson Production at the LHC as a Probe of Double Parton Scattering [PDF]

open access: yes, 1999
Double parton scattering, i.e. two parton hard scattering processes in the same hadron-hadron collision, may constitute an important background for Higgs and other new particle searches at the LHC. We point out that like-sign W pair production provides a

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.

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.
