The multiple scattering contribution to fixed-angle elastic hadron-hadron scattering

open access: yesNuclear Physics B, 1991
Abstract Using the factorized form of the leading behavior (in powers of Q) of fixed-angle elastic hadron-hadron scattering given by Botts and Sterman, the leading perturbative QCD contribution to dσ/dt (ϑ = π/2) for pions and protons is numerically evaluated.

Differential cross-section measurements of the production of four charged leptons in association with two jets using the ATLAS detector

open access: yesJournal of High Energy Physics
Differential cross-sections are measured for the production of four charged leptons in association with two jets. These measurements are sensitive to final states in which the jets are produced via the strong interaction as well as to the purely ...

Measurements of WH and ZH production with Higgs boson decays into bottom quarks and direct constraints on the charm Yukawa coupling in 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics
A study of the Higgs boson decaying into bottom quarks (H → b b ¯ $$ b\overline{b} $$ ) and charm quarks (H → c c ¯ $$ c\overline{c} $$ ) is performed, in the associated production channel of the Higgs boson with a W or Z boson, using 140 fb −1 of proton-

Search for same-charge top-quark pair production in pp collisions at s $$ \sqrt{\textrm{s}} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for the production of top-quark pairs with the same electric charge (tt or tt ¯ $$ \overline{tt} $$ ) is presented. The analysis uses proton-proton collision data at s $$ \sqrt{s} $$ = 13 TeV, recorded by the ATLAS detector at the Large Hadron ...

Search for a CP-odd Higgs boson decaying into a heavy CP-even Higgs boson and a Z boson in the ℓ + ℓ − t t ¯ $$ {\ell}^{+}{\ell}^{-}t\overline{t} $$ and ν ν ¯ b b ¯ $$ \nu \overline{\nu}b\overline{b} $$ final states using 140 fb −1 of data collected with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a heavy CP-odd Higgs boson, A, decaying into a Z boson and a heavy CP-even Higgs boson, H, is presented. It uses the full LHC Run 2 dataset of pp collisions at s $$ \sqrt{s} $$ = 13 TeV collected with the ATLAS detector, corresponding to an ...

COMPASS - a facility to study QCD

open access: yes, 2011
An overview on the new COMPASS II experimental programme is presented. The main topics include a study of Primakoff reactions, generalised parton distributions via deeply virtual Compton scattering and transverse momentum dependent distributions in Drell-

Search for new particles in final states with a boosted top quark and missing transverse momentum in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for events with one top quark and missing transverse momentum in the final state is presented. The fully hadronic decay of the top quark is explored by selecting events with a reconstructed boosted top-quark topology produced in association with

Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons in proton–proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for the resonant production of a heavy scalar X decaying into a Higgs boson and a new lighter scalar S, through the process X → S(→ b b ¯ $$ b\overline{b} $$ )H(→γγ), where the two photons are consistent with the Higgs boson decay, is performed.
