| Resumen |
We present measurements of asymmetries in angular distributions of leptons produced in tt¯ events in proton-antiproton collisions at the Fermilab Tevatron Collider. We consider final states where the W± bosons from top quark and antiquark decays both decay into ℓν (ℓ=e, μ) resulting in oppositely charged dilepton final states with accompanying jets. Using 9.7 fb−1 of integrated luminosity collected with the D0 detector, we find the asymmetries in lepton pseudorapidity compatible with predictions based on the standard model. |
