Summary
We measure the forward--backward asymmetry of the production of top-quark and antiquark pairs in proton-antiproton collisions at center-of-mass energy $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ using the full data set collected by the Collider Detector at Fermilab (CDF) in Tevatron Run II corresponding to an integrated luminosity of $9.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The asymmetry is characterized by the rapidity difference between top quarks and antiquarks ($\mathrm{\ensuremath{\Delta}}y$) and measured in the final state with two charged leptons (electrons and muons). The inclusive asymmetry, corrected to the entire phase space at parton level, is measured to be ${A}_{\mathrm{FB}}^{t\overline{t}}=0.12\ifmmode\pm\else\textpm\fi{}0.13$, consistent with the expectations f
