Improved Spin Basis for Angular Correlation Studies in Single Top Quark Production at the Tevatron [PDF]

open access: yes, 1996
We show in single top quark production that the spin of the top quark is correlated with the direction of the d-type quark in the event. For single top production in the W* channel, the d-type quark comes dominantly from the antiproton at the Tevatron ...

Recent results on top quark mass and properties and rare/anomalous top quarks interactions in CMS

open access: yesSciPost Physics Proceedings, 2022
The amount of data collected by the CMS experiment at the CERN LHC in the second data taking period provides the possibility to study absolute and differential cross sections of top quark interaction processes with high precision.

Tumbling top-quark condensate model [PDF]

open access: yesPhysical Review D, 1992
We propose a renormalizable model with no fundamental scalars which breaks itself in the manner of a "tumbling" gauge theory down to the standard model with a top-quark condensate. Because of anomaly cancellation requirements, this model contains two color sextet fermions (quixes), which are vector-like with respect to the standard model gauge group ...

Top Quark Studies at D0

open access: yes, 2014
Years after its discovery in 1995 by CDF and D0, the top quark still undergoes intense investigations at the Tevatron. Using up to the full Run~II data sample, new measurements of top quark production and properties by the D0 Collaboration are presented.

Precision Measurements of Top Quark Production with the ATLAS Detector

open access: yesEPJ Web of Conferences, 2017
The top quark is the heaviest known fundamental particle. It is the only quark that decays before it hadronises which gives us the unique opportunity to probe the properties of bare quarks and to test perturbative QCD.

Top quark mass studies with t t ¯ j $$ t\overline{t}j $$ at the LHC

open access: yesJournal of High Energy Physics, 2018
A precise measurement of the top quark mass, a fundamental parameter of the Standard Model, is among the most important goals of top quark studies at the Large Hadron Collider.

Measurement of the top quark mass with the ATLAS detector using tt¯ events with a high transverse momentum top quark

open access: yesPhysics Letters B
The mass of the top quark is measured using top-quark-top-antiquark pair events with high transverse momentum top quarks. The dataset, collected with the ATLAS detector in proton–proton collisions at s=13 TeV delivered by the Large Hadron Collider ...

Top quark property at Tevatron

open access: yesEPJ Web of Conferences, 2013
The top quark, the heaviest known elementary particle, remains by far the most interesting particle to test standard model as well as search new physics beyond standard model because of its large mass and unique properties. Having data collected about 10
