title = "From Tevatron's top and lepton-based asymmetries to the LHC",
abstract = "We define a lepton-based asymmetry in semi-leptonic t t{\= } production at the LHC. We show that the ratio of this lepton-based asymmetry and the t t{\= } charge asymmetry, measured as a function of the lepton transverse momentum or the t t{\= } invariant mass is a robust observable in the Standard Model. It is stable against higher order corrections and mis-modeling effects. We show that this ratio can be also a powerful discriminant among different models of new physics and between them and the Standard Model. Finally, we show that a related ratio defined at the Tevatron is also robust as a function of the t t{\= } invariant mass.",
