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^…
