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 ...

Infrared subtraction at next-to-next-to-leading order for gluonic initial states [PDF]

open access: yes, 2010
In this thesis we describe a procedure for isolating the infrared singularities present in gluonic scattering amplitudes at next-to-leading and next-to-next-to-leading order.

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 ...

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 higgsinos in compressed mass spectra using low-momentum tracks in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
This paper presents two searches for the electroweak production of higgsinos with compressed mass spectra using 140 fb −1 of s = 13 $$ \sqrt{s}=13 $$ TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider.

Measurement of the |V cb | element of the CKM matrix in t t ¯ $$ t\overline{t} $$ decays with the ATLAS detector

open access: yesJournal of High Energy Physics
The first measurement of the magnitude of the CKM quark mixing matrix element |V cb | using on-shell W-boson decays is presented. The measurement is made with t t ¯ $$ t\overline{t} $$ events from pp collision data corresponding to an integrated ...

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.
