Measurement of the jet mass in highly boosted $${\mathrm{t}}\overline{\mathrm{t}}$$ t t ¯ events from pp collisions at $$\sqrt{s}=8$$ s = 8 $$\,\text {TeV}$$ TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
The first measurement of the jet mass $$m_{\text {jet}}$$ m jet of top quark jets produced in $${\mathrm{t}}\overline{\mathrm{t}} $$ t t ¯ events from pp collisions at $$\sqrt{s}=8$$ s = 8 $$\,\text {TeV}$$ TeV is reported for the jet with the largest ...

Measurements of differential cross sections of top quark pair production in association with jets in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV using the ATLAS detector

open access: yesJournal of High Energy Physics, 2018
Measurements of differential cross sections of top quark pair production in association with jets by the ATLAS experiment at the LHC are presented. The measurements are performed as functions of the top quark transverse momentum, the transverse momentum ...

Quantum entanglement and top spin correlations in SMEFT at higher orders

open access: yesJournal of High Energy Physics, 2023
We present the first analysis of top spin polarizations, t t ¯ $$ t\overline{t} $$ spin correlations, and t t ¯ $$ t\overline{t} $$ spin entanglement at the LHC in the context of the Standard Model Effective Field Theory, that goes beyond Leading Order ...

Polarization of the top quark as a probe of its chromomagnetic and chromoelectric couplings in single-top production at the Large Hadron Collider [PDF]

open access: yes, 2015
We study the sensitivity of the Large Hadron Collider, LHC, to top quark chromomagnetic, CMDM, and chromoelectric, CEDM, dipole moments and Wtb effective couplings in singletop production in association with a W, boson, followed by semileptonic decay of ...

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 ...

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

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
