We present the first simultaneous measurement of the ratio of branching fractions, R=B(t --> Wb)/B(t --> Wq), with q being a d, s, or b quark, and the top-quark pair production cross section sigma(tt[over]) in the lepton plus jets channel using 0.9 fb(-1) of pp[over] collision data at sqrt(s)=1.96 TeV collected with the D0 detector. We extract R and sigma(tt[over]) by analyzing samples of events with 0, 1, and > or =2 identified b jets. We measure R=0.97(+0.09)/(-0.08)(stat+syst) and sigma(tt… Expand

TLDR
Experimental measurements of the top quark mass accomplished at the Tevatron, a proton-antiproton collider located at the Fermi National Accelerator Laboratory, are described and data analysis techniques used to extract information about the top mass are reviewed. Expand
Model-independent extraction of |Vtq| matrix elements from top-quark measurements at hadron colliders
Current methods to extract the quark-mixing matrix element |Vtb| from single-top-production measurements assume that |Vtb|≫|Vtd|,|Vts|: top quarks decay into b quarks with 100 % branching fraction,Expand
Probing the flavor of the top quark decay
The top quark sector is almost decoupled from lighter quark generations due to the fact that $V_{tb}\approx$~1. The current experimental measurements of $V_{tb}$ are compatible with the StandardExpand

With the full Tevatron Run II and early LHC data samples, the opportunity for furthering our understanding of the properties of the top quark has never been more promising. Although the currentExpand
Status and prospects of top-quark physics
Abstract The top quark is the heaviest elementary particle observed to date. Its large mass of about 173 GeV/ c 2 makes the top quark act differently than other elementary fermions, as it decaysExpand
