Description

We measure the asymmetry of the lepton in semileptonic ttbar decays in the full Run II sample of 9.4/fb. We develop a new technique to correct for the incomplete lepton acceptance and derive a parton-level asymmetry. The result of Afb(lep) = 0.094^{+0.032}_{-0.029} is approximately 2σ above the current Standard Model NLO prediction of Afb(lep) = 0.036.
