Up and Down Quark Structure of the Proton

D0 Collaboration

We measure proton structure parameters sensitive primarily to valence quarks using 8.6 fb $^{- 1}$ of data collected by the D0 detector in $s = 1.96$ TeV $p p ˉ$ collisions a…

Measurement of the Effective Weak Mixing Angle in $p p ˉ \to Z / γ^{*} \to ℓ^{+} ℓ^{-}$ Events

D0 Collaboration

We present a measurement of the effective weak mixing angle parameter $sin^{2} θ_{eff}^{ℓ}$ , in $p p ˉ \to Z / γ^{*} \to μ^{+} μ^{-}$ events at a center of mass ener…

Evidence for a $B_{s}^{0} π^{\pm}$ State

D0 Collaboration

We report evidence of a narrow structure, $X (5568)$ , in the decay sequence $X (5568) \to B_{s}^{0} π^{\pm}$ , $B_{s}^{0} \to J / ψ ϕ$ , $J / ψ \to μ^{+} μ^{-}$ , $ϕ\rightarrow K^…

Evidence for simultaneous production of $J / ψ$ and $Υ$ mesons

D0 Collaboration

We report evidence for the simultaneous production of $J / ψ$ and $Υ$ mesons in 8.1 fb $^{- 1}$ of data collected at $s =$ 1.96 TeV by the D0 experiment at the Fermilab $p p ˉ$ …

Measurement of the ratio of inclusive cross sections $σ (p p ˉ \to Z + 2 b jets) / σ (p p ˉ \to Z + 2 jets)$ in $p p ˉ$ collisions at $s = 1.96$ TeV

D0 Collaboration

We measure the ratio of cross sections, $σ (p p ˉ \to Z + 2 b jets)$ / $σ (p p ˉ \to Z + 2 jets)$ , for associated production of a $Z$ boson with at least…

D0 Collaboration

We present a measurement of the distribution of the variable $ϕ_{η}^{*}$ for muon pairs with masses between 30 and 500 GeV, using the complete Run II data set collected by the D0 detec…
