Top quark mass measurements at D0
We present the most recent measurements of the mass of the top quark at D0 using proton-antiproton collisions at √ s = 1.96 TeV at the Fermilab Tevatron collider. The world average for the mass of the top quark is 170.9 ± 1.8 GeV/c.
متن کاملTop quark property measurements at the Tevatron
We review recent measurements of the properties of the top quark by the CDF and D0 experiments: the mass and decay width of the top quark, the ratio R = Bt→Wb/Bt→Wq, the total production cross section of tt pairs, the helicity of the W boson, anomalous couplings at the Wtb vertex, the asymmetry of tt production due to the colour charge, and the first study of the top quark polarisation. The mea...
متن کاملMeasurements of top quark decay properties
I report on measurements of the properties of the top quark using data collected by the CDF and DØ detectors during Run II of the Fermilab Tevatron. The helicity of the W boson arising from top quark decay, the top quark decay branching ratios, and the top quark charge have all been measured, and the results in all cases are consistent with standard model expectations.
متن کاملTop Quark Mass Measurements at the Tevatron
The general strategy, as well as channel-specific details, applied to the measurement of the top quark mass at the Tevatron in Run I are reviewed, and the combination of the results obtained by the CDF and DØ collaborations presented. The accelerator and detector upgrades for Run II are described, and expected improvements in the systematic uncertainties on the measurement evaluated.
متن کاملTop Quark Mass Measurements at CDF
Recent measurements of the mass of the top quark (t) are presented using 162 pb of data of pp collisions at √ s = 1.96TeV collected by the CDF detector at the Tevatron collider during Run II. The analyses focus on the semi-leptonic decay mode tt̄ → (blν)(bqq̄) with one or two identified bottom quarks (b). The Template Method (TM) reconstructs the invariant mass of the top quark in each event. The...
