Measurement of the leptonic asymmetry in tt̄ events produced in pp̄ collisions at √s=1.96 TeV

Journal Article (Journal Article)

We measure the asymmetry in the charge-weighted rapidity qyℓ of the lepton in semileptonic tt̄ decays recorded with the CDF II detector using the full Tevatron Run II sample, corresponding to an integrated luminosity of 9.4 fb-1. A parametrization of the asymmetry as a function of qyℓ is used to correct for the finite acceptance of the detector and recover the production-level asymmetry. The result of AFBℓ=0.094-0.029+0.032 is to be compared to the standard model next-to-leading-order prediction of AFBℓ=0.038±0.003. © 2013 American Physical Society.
