Measurement of the Top Quark Mass in the Dilepton Final State using the Matrix Element Method [PDF]

open access: yes, 2008
The top quark, discovered in 1995 by the CDF and D0 experiments at the Fermilab Tevatron Collider, is the heaviest known fundamental particle. The precise knowledge of its mass yields important constraints on the mass of the yet-unobserved Higgs boson ...

TOP QUARK MEASUREMENTS [PDF]

open access: yesInternational Journal of Modern Physics A, 2006
Ten years after its discovery at the Tevatron collider, we still know little about the top quark. Its large mass suggests it may play a key role in the mechanism of Electroweak Symmetry Breaking (EWSB), or open a window of sensitivity to new physics related to EWSB and preferentially coupled to it.

TOP QUARK PHYSICS AT THE TEVATRON [PDF]

open access: yesInternational Journal of Modern Physics A, 2013
The heaviest known elementary particle, the top quark, was discovered in 1995 by the CDF and D0 collaborations at the Tevatron proton–antiproton collider at Fermilab. Since its discovery, a large program was set in motion by the CDF and D0 collaborations to characterize the production and decay properties of top quarks, and investigate their potential ...

Measurements of top quark pair relative differential cross-sections with ATLAS in pp collisions at s√=7 TeV [PDF]

open access: yes, 2013
Measurements are presented of differential cross-sections for top quark pair production in pp collisions at s√=7 TeV relative to the total inclusive top quark pair production cross-section. A data sample of 2.05 fb−1 recorded by the ATLAS detector at the

On the top-quark width measurement using a combination of resonant and non resonant cross sections.

open access: yesEPJ Web of Conferences, 2017
Top quark width measurement is important and complex task. Most measurements are done in assumption of the SM top quark interactions. We would like to discuss model independent way of measuring the top quark width.

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 ...

Measurement of the top-quark mass in all-jets [Formula: see text] events in pp collisions at [Formula: see text] TeV. [PDF]

open access: yesEur Phys J C Part Fields, 2014
The mass of the top quark is measured using a sample of $\text{t}\bar{\mathrm{t}}$ candidate events with at least six jets in the final state. The sample is selected from data collected with the CMS detector in pp collisions at $\sqrt{s}$ = 7 TeV in ...
