No. of bitstreams: 0 Previous issue date: 2008-05-14; 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 σtt̄ in the lepton plus jets channel using 0.9fb-1 of pp̄ collision data at s=1.96TeV collected with the D0 detector. We ...

No. of bitstreams: 0 Previous issue date: 2010-06-17; Science and Technology Facilities Council; Using 5.4fb-1 of integrated luminosity from pp̄ collisions at √s=1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider, we search for decays of the lightest Kaluza-Klein mode of the graviton in the Randall-Sundrum model to ee and γγ. We set 95...
