Measurement of the inclusive leptonic asymmetry in top-quark pairs that decay to two charged leptons at CDF

We measure the inclusive forward-backward asymmetry of the charged-lepton pseudorapidities from top-quark pairs produced in proton-antiproton collisions, and decaying to final states that contain two charged leptons (electrons or muons), using data collected with the Collider Detector at Fermilab. With an integrated luminosity of 9.1 ${\mathrm{f}\mathrm{b}}^{-1}$, the leptonic forward-backward asymmetry, $A_{\text{FB}}^{\mathrm{\ell }}$, is measured to be $0.072\pm 0.060$ and the leptonic pair forward-backward asymmetry, $A_{\text{FB}}^{\mathrm{\ell }\mathrm{\ell }}$, is measured to be $0.076\pm 0.082$, compared with the standard model predictions of $A_{\text{FB}}^{\mathrm{\ell }}=0.038\pm 0.003$ and $A_{$\text{FB}$}^{\ell\ell} = 0.048 \pm 0.004$,respectively\mathrm{.}Additionally,wecombinethe$A_{$\text{FB}$}^{\ell}$ result with a previous determination from a final state with a single lepton and hadronic jets and obtain $A_{$\text{FB}$}^{\ell} = 0.090^{+0.028}_{-0.026}$.
