Top-quark mass measurement in the all-hadronic t t ¯ $$ t\overline{t} $$ decay channel at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
The top-quark mass is measured in the all-hadronic top-antitop quark decay channel using proton-proton collisions at a centre-of-mass energy of s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector at the CERN Large Hadron Collider. The data set used in the

Top quark pair properties: spin correlation, charge asymmetry and complex final states at LHC in ATLAS

open access: yesEPJ Web of Conferences, 2013
In proton–proton collisions at the LHC, pairs of top and anti-top quarks are expected to be mostly produced through gluon fusion, in contrast to production at the Tevatron, where quark annihilation dominates.

Reconstruction of top-quark mass effects in Higgs pair production and other gluon-fusion processes

open access: yesJournal of High Energy Physics, 2018
We propose a novel method for the treatment of top-quark mass effects in the production of H (∗), HH, HZ and ZZ final states in gluon fusion. We show that it is possible to reconstruct the full top-quark mass dependence of the virtual amplitudes from the

The significance of the heavy top quark [PDF]

open access: yesAIP Conference Proceedings, 1997
Experiment shows that the top quark is far heavier than the other elementary fermions. This finding has stimulated research on theories of electroweak and flavor symmetry breaking that include physics beyond the standard model. Efforts to accommodate a heavy top quark within existing frameworks have revealed constraints on model-building.

ATLAS top quark results

open access: yes, 2017
The top quark is the heaviest known fundamental particle. As it is the only quark that decays before it hadronises, analyses of events containing top quarks allow to probe the properties of bare quarks and to test perturbative QCD.
