Combination of the Top Quark Mass Measurements from the Tevatron Collider
(American Physical Society, 2012)
The top quark is the heaviest known elementary particle, with a mass about 40 times larger than the mass of its isospin partner, the bottom quark. It decays almost 100% of the time to a W boson and a bottom quark. Using ...
Improved Determination of the Width of the Top Quark
(American Physical Society, 2012-05)
We present an improved determination of the total width of the top quark, Γt, using 5.4 fb-1 of integrated luminosity collected by the D0 Collaboration at the Tevatron pp- Collider. The total width Γt is extracted from ...
Search for Violation of Lorentz Invariance in Top Quark Pair Production and Decay
(American Physical Society, 2012-06-29)
Using data collected with the D0 detector at the Fermilab Tevatron Collider, corresponding to 5:3 fb-1 of integrated luminosity, we search for violation of Lorentz invariance by examining the tt production cross section ...
