Top quark physics at the LHC

open access: yesEPJ Web of Conferences, 2014
In 2011, an integrated luminosity of more than 5 fb−1 at 7 TeV has been delivered by the LHC. The measurement of the cross section in top quark pair production and in single top quark production, top quark mass, top quark properties and new physics ...

Top-quark properties and mass measurements with the ATLAS detector

open access: yesEPJ Web of Conferences, 2018
The top quark is unique among the known quarks in that it decays before it has an opportunity to form hadronic bound states. This makes measurements of its properties particularly interesting as one can access directly the properties of a bare quark. The

Studying Same-Sign Top Pair Production through Top-Higgs FCNC Interactions at the HL-LHC

open access: yesAdvances in High Energy Physics, 2022
We investigate the potential of the HL-LHC for discovering new physics effects via the same-sign top pair signatures. We focus on the semileptonic (electron and muon) decay of the top quarks and study the reach for a simplified model approach where top ...

TOP QUARK PHYSICS [PDF]

open access: yesInternational Journal of Modern Physics A, 2008
A review is presented of the current experimental status of the top quark sector of the Standard Model. The measurements summarized include searches for electroweak single top production, the latest results on the [Formula: see text] production cross-section, and searches for new physics in top quark production and decay.

THE TOP QUARK [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 1996
▪ Abstract  Since the discovery of the bottom quark in 1977, physicists have searched for the top quark, the weak isospin partner of the bottom quark. Indirect evidence and estimates of its mass have been made; however, direct observation eluded scientists until recently.

Invariant-mass distribution of top-quark pairs and top-quark mass determination * [PDF]

open access: yesChinese Physics C, 2020
Abstract In this study, we investigate the invariant-mass distribution of top-quark pairs near the 2mt threshold, which strongly influences the determination of the top-quark mass mt . Higher-order non-relativistic corrections lead to large contributions, which are not included in the state-of-the-art

Search for direct top-squark pair production in final states with two leptons in pp collisions at √s = 8 TeV with the ATLAS detector [PDF]

open access: yes, 2014
A search is presented for direct top-squark pair production in final states with two leptons (electrons or muons) of opposite charge using 20.3 fb−1 of pp collision data at s√ = 8 TeV, collected by the ATLAS experiment at the Large Hadron Collider in ...

Bottom-quark fragmentation in top-quark decay [PDF]

open access: yesNuclear Physics B, 2002
We study the fragmentation of the b quark in top decay in NLO QCD, within the framework of perturbative fragmentation, which allows one to resum large logarithms $\sim\log (m_t^2/m_b^2)$. We show the b-energy distribution, which we compare with the exact ${\cal O} (α_S)$ result for a massive b quark.

Top-quark physics at the CLIC electron-positron linear collider

open access: yesJournal of High Energy Physics, 2019
The Compact Linear Collider (CLIC) is a proposed future high-luminosity linear electron-positron collider operating at three energy stages, with nominal centre-of-mass energies s $$ \sqrt{s} $$ = 380 GeV, 1.5 TeV, and 3 TeV.
