Events are selected with a single lepton (electron or muon), missing transverse momentum and at least four jets of which at least one jet is identified as coming from a b-quark. A kinematic fit is used to reconstruct the t (t) over bar event topology. After background subtraction, a Bayesian unfolding procedure is performed to correct for acceptance and detector effects. The measured value of A(C) is A(C) =-0.019+/-0.028 (stat.)+/-0.024 (syst.), consistent with the prediction from the MC@NLO Monte Carlo generator of A(C) = 0.006+/-0.002. Measurements of AC in two ranges of invariant mass of the top-antitop pair are also shown.", optnote="WOS:000306059600018", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1110), last updated on Mon, 27 Aug 2012 18:31:06 +0000", issn="1434-6044", doi="10.1140/epjc/s10052-012-2039-5", opturl="http://arxiv.org/abs/1203.4211", opturl="https://doi.org/10.1140/epjc/s10052-012-2039-5", archivePrefix="arXiv", eprint="1203.4211", language="English" }
