Properties of the Top Quark

open access: yesUniverse
Recent measurements of the properties of the top quark at the CERN Large Hadron Collider are discussed. The results were measured for single and top quark pair production in their final states, including jets with either one or two leptons or only in ...

Measurement of the top quark charge in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2013
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb−1 of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined

Search for top quark decays t → qH with H → γγ using the ATLAS detector [PDF]

open access: yes, 2014
A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons.

A search for flavour changing neutral currents in top-quark decays in pp collision data collected with the ATLAS detector at s√=7TeV [PDF]

open access: yes, 2012
A search for flavour changing neutral current (FCNC) processes in top-quark decays by the ATLAS Collaboration is presented. Data collected from pp collisions at the LHC at a centre-of-mass energy of s√=7TeV during 2011, corresponding to an integrated ...

Top quark decays into heavy quark mesons [PDF]

open access: yesPhysical Review D, 1996
For top quark decays into heavy quark mesons $Υ$ and $\bar{B}_c^*$ , a complete calculation to the leading order both in QCD coupling constant $α_s$ and in $v$, the typical velocity of the heavy quarks inside the mesons, is performed. Relatons between the top quark mass and the decay branching ratios are studied.

THE SINGLE TOP QUARK PHYSICS [PDF]

open access: yesInternational Journal of Modern Physics A, 2012
The single top quark production has an electroweak nature and provides an additional support to the top pair production source of the top quarks. The processes involving single top have unique properties and are very interesting from both theoretical and experimental viewpoints.
