Up and down quark structure of the proton Open
We report an improved measurement of the valence u and d quark distributions from the forward-backward asymmetry in the Drell-Yan process using 8.6 fb−1 of data collected with the D0 detector in pp¯ collisions at s=1.96. This analysis pro…

Studies of $X(3872)$ and $\psi(2S)$ production in $p\bar{p}$ collisions at 1.96 TeV Open
We present various properties of the production of the $X(3872)$ and $ψ(2S)$ states based on $10.4 fb^{−1}$ collected by the D0 experiment in Tevatron $p\bar{p}$ collisions at $\sqrt{s}=1.96 TeV$. For both states, we measure the nonprompt …

Tevatron Run II combination of the effective leptonic electroweak mixing angle Open
Drell-Yan lepton pairs produced in the process $p\bar{p} → ℓ^+ ℓ^−$ + X through an intermediate γ∗/Z boson have an asymmetry in their angular distribution related to the spontaneous symmetry breaking of the electroweak force and the associ…

Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron Open
The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These…

Combination of D0 measurements of the top quark mass Open
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992–1996) at √s=1.8 TeV and Run II (2001–2011) at √s = 1.96 TeV of the T…

Measurement of the top quark mass using the matrix element technique in dilepton final states Open
We present a measurement of the top quark mass in p (p) over bar collisions at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. The data were collected by the D0 experiment corresponding to an integrated luminosity of…

ATLAS strategy for primary vertex reconstruction during Run-2 of the LHC Open
The reconstruction of vertices corresponding to proton--proton collisions in ATLAS is an essential element of event reconstruction used in many performance studies and physics analyses. During Run-1 of the LHC, ATLAS has employed an iterat…

CP Violation in the $B_s^0$ system Open
We review experimental and theoretical aspects of CP violation in the $B_s^0$-system. In that respect we present updates for the mixing parameters of the $B_s^0$ mesons expected in the Standard Model (SM): the mass difference $ΔM_s^{\rm SM…

Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting Open
We measure the top quark mass in dilepton final states of t (t) over bar events in p (p) over bar collisions at root s = 1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb(-1) at the Fermilab Tevatron Collider. The an…
