We report the combination of recent measurements of the helicity of the W boson from top quark decay by the CDF and D0 collaborations, based on data samples corresponding to integrated luminosities of $2.7-5.4\text{ ... • (American Physical Society, 2012) We present the results of the combination of searches for the standard model Higgs boson produced in association with a$W$or$Z$boson and decaying into$b\bar{b}$using the data sample collected with the D0 detector in ... • (American Physical Society, 2012) We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a$W$or$Z$boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating ... • (American Physical Society, 2012) We present a measurement of the ratio of events with correlated$t$and$\bar{t}$spins to the total number of$t\bar{t}$events. This ratio$f$is evaluated using a matrix-element-based approach in 729$t\bar{t}$candidate ... • (Indiana University Cyclotron Facility, 1984) • (American Physical Society, 2012) We present an improved determination of the total width of the top quark,$\Gamma_t$, using$5.4  \text{fb}^{−1}$of integrated luminosity collected by the D0 Collaboration at the Tevatron$p\bar p$Collider. The total ... • (American Physical Society, 2012) We measure the$\Lambda^0_b$lifetime in the fully reconstructed decay$\Lambda^0_b\rightarrow J/\psi\Lambda^0$using$10.4  \text{fb}^{−1}$of$p\bar p$collisions collected with the D0 detector at$\sqrt s=1.96  \text{TeV}$. ... • (American Physical Society, 2012) We report an updated measurement of the$CP$-violating phase,$\phi^{J/\psi\phi}_s$, and the decay-width difference for the two mass eigenstates,$\Delta\Gamma_s$, from the flavor-tagged decay$B^0_s\rightarrow J/\psi\phi$. ... • (American Physical Society, 2012) We present a measurement of the$W$boson mass using data corresponding to$4.3 \text{ fb}^{−1}$of integrated luminosity collected with the D0 detector during Run II at the Fermilab Tevatron$p\bar p$collider. With a ... • (American Physical Society, 2012) We study the processes$p\bar p \rightarrow WZ \rightarrow ℓ^{±}\nu ℓ^{+}l^{-}$and$p\bar p \rightarrow ZZ \rightarrow ℓ^{+}ℓ^{−}\nu\bar\nu$, where$ℓ=e$or$\mu$. Using$8.6 \text{ fb}^{−1}$of integrated luminosity ... • (American Physical Society, 2012) We present a measurement of the elastic differential cross section$d\sigma(p\bar p \rightarrow p\bar p)/dt$as a function of the four-momentum-transfer squared t. The data sample corresponds to an integrated luminosity ... • (American Physical Society, 2012) We present a measurement of the inclusive jet cross section using the Run II cone algorithm and data collected by the D0 experiment in$p\bar p$collisions at a center-of-mass energy$\sqrt s=1.96\ \text{TeV}$, corresponding ... • (American Physical Society, 2012) We present a measurement of the relative branching fraction,$R_{f_0/\phi}$, of$B^0_s\rightarrow J/\psi f_0(980)$, with$f_0(980)→\pi^+\pi^−$, to the process$B^0_s→J/\psi\phi$, with$ϕ→K^+K^−$. The$J/\psi f_0(980)$final ... • (American Physical Society, 2012) We present a measurement of the top-quark mass$(m_t)$in$p\bar p$collisions at$\sqrt s=1.96  \text{TeV}$using$t\bar t$events with two leptons$(ee, eμ, or μμ)$and accompanying jets in$4.3  \text{fb}^{−1}$of data ... • (American Physical Society, 2012) We study$WW$and$WZ$production with$ℓνqq\ (ℓ=e,μ)$final states using data collected by the D0 detector at the Fermilab Tevatron Collider corresponding to$4.3  \text{fb}^{−1}$of integrated luminosity from$p\bar p\$ ...

We describe a model-independent search for physics beyond the standard model in lepton final states. We examine 117 final states using 1.1fb -1 of pp̄ collisions data at √s=1.96TeV collected with the D0 detector. We conclude ...
• (American Physical Society, 2012)
Using data corresponding to an integrated luminosity of 1.3fb -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 photon ...
