We present a measurement of the W boson mass using data corresponding to 4:3 fb-1 of integrated luminosity collected with the D0 detector during Run II at the Fermilab Tevatron pp collider. With a sample of 1 677 394 W ...

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 ...

We present a measurement of the top-quark mass (mt) in pp- collisions at √s=1.96TeV using tt- events with two leptons (ee, e μ, or μμ) and accompanying jets in 4.3 fb-1 of data collected with the D0 detector at the ...

The combination of searches performed by the CDF and D0 collaborations at the Fermilab Tevatron Collider for neutral Higgs bosons produced in association with b quarks is reported. The data, corresponding to 2 : 6fb 1 of ...

We measure the Λ0/b lifetime in the fully reconstructed decay Λ 0b→J/Ψ Λ0 using 10.4 fb-1 of pp- collisions collected with the D0 detector at √s=1.96TeV. The lifetime of the topologically similar decay channel B0→J/ΨK0S ...

We investigate the decay B0s→JΨK+K- for invariant masses of the K+K- for invariant masses of the K+K- pair in the range 1.35<M(K+K-) < 2GeV. The data sample corresponds to an integrated luminosity of 10.4fb-1 of pp- ...

We present the first search for new phenomena in Zγ final states with large missing transverse energy using data corresponding to an integrated luminosity of 6.2 fb-1 collected with the D0 experiment in pp- collisions ...

Using data corresponding to an integrated luminosity of 1:3 fb-1, we observe a narrow mass state decaying into Υ (1S) + γ, where the Υ(1S) meson is detected by its decay into a pair of oppositely charged muons, and the ...

We present a measurement of the elastic differential cross section dσ( pp-→ pp-)/dt as a function of the four-momentum-transfer squared t. The data sample corresponds to an integrated luminosity of ≈ 31 nb-1 collected ...

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 ...
