Measurement of the W Boson Mass with the D0 Detector
(American Physical Society, 2012-04)
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 ...
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 ...
Measurement of the Top-Quark Mass in pp- Collisions Using Events with Two Leptons
(American Physical Society, 2012-09)
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 ...

Measurement of the Λ0b Lifetime in the Exclusive Decay Λ0b→J/ΨΛ0 in pp- Collisions at √s=1.96TeV
(American Physical Society, 2012-06)
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 ...
Study of the Decay B0s→ J.lΨf̕2 (1525) in μ+μ-K+K- Final States
(American Physical Society, 2012)
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- ...
Search for Zγ Events with Large Missing Transverse Energy in pp- Collisions at √s=1.96TeV
(American Physical Society, 2012-10)
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 ...
Observation of a Narrow Mass State Decaying Into Υ(1S) + γ in pp- Collisions at √s = 1.96 TeV
(American Physical Society, 2012)
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 ...
Measurement of the Differential Cross Section dσ/dt in Elastic pp- Scattering at √s = 1.96 TeV
(American Physical Society, 2012)
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 ...
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 ...
