Description
The top quark is the heaviest fundamental particle known to date. More than 10 years after its discovery at the Tevatron proton-antiproton collider, recently recorded datasets from the Tevatron are available which are seventy times larger than those used for the discovery. These datasets allow measurements of top quark properties that were not possible before such as the first evidence for electroweak production of top quarks and the resulting direct constraints on the involved couplings. In addition, improved measurements of top quark properties provide more stringent tests of predictions from the Standard Model of elementary particle physics. In particular, the improvement in measurements of the mass of the top quark, with the latest uncertainty of 0.7% marking the most precisely measured quark mass to date, further constrains the prediction of the mass of the still to be discovered Higgs boson.
