We present the derivation of the NNLO two-parton final state contributions to top pair production in the quark-antiquark channel proportionnal to the leading colour factor N 2 c . Together with the three and four-parton NNLO contributions presented in a previous publication, this enables us to complete the phenomenologically most important NNLO corrections to top pair hadro-production in this channel. We derive this two-parton contribution using the massive extension of the NNLO antenna subtraction formalism and implement those corrections in a parton-level event generator providing full kinematical information on all final state particles. In addition, we also derive the heavy quark contributions proportional to N h . Combining the new leading-colour and heavy quark contributions together with the light quark contributions derived previously, we present NNLO differential distributions for LHC and Tevatron. We also compute the differential top quark forward-backward asymmetry at Tevatron and find that our results are in good agreement with the measurements by the D0 collaboration.

Probing the top-quark chromomagnetic dipole moment at next-to-leading order in QCD

We present predictions at NLO accuracy in QCD for top-quark pair production induced by an anomalous chromomagnetic dipole moment of the top quark. Our results are obtained for total as well as fully differential cross sections, including matching to parton shower simulations. This process is expected to provide the most stringent direct limits on top-quark chromomagnetic dipole moment. We find that NLO corrections increase the contribution from the dipole moment by about 50% at the LHC, and significantly reduce the renormalization and factorization scale dependence. Using the NLO prediction, we update the current limit from the Tevatron and the LHC measurements. Apart from total cross section, we also study other observables relevant for LHC phenomenology.

“…With the CDF data, corresponding to 9.4 fb −1 of integrated luminosity, the measurement in the lepton+jets final state yielded a value of 0.164 ± 0.047 [11], which is consistent with the NNLO SM prediction [6] within 1.5σ. The same measurements with data from the D0 collaboration corresponding to 9.7 fb −1 of integrated luminosity in the lepton+jets [12] and dilepton final state [13] yielded 0.106 ± 0.030 and 0.175 ± 0.063, respectively, which are consistent with the NNLO SM prediction [6]. The differential A tt FB measurements as functions of the invariant mass of tt (m tt ) and ∆y at CDF in the lepton+jets final state [11] showed mild tension (2.4σ and 2.8σ, respectively) with the SM predictions, while the results in the D0 lepton+jets final state [12] showed consistency (within 1σ).…”

We measure the forward-backward asymmetry of the production of top quark and antiquark pairs in proton-antiproton collisions at center-of-mass energy √ s = 1.96 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 fb −1 . The asymmetry is characterized by the rapidity difference between top quarks and antiquarks (∆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 tt FB = 0.12 ± 0.13, consistent with the expectations from the standard-model (SM) and previous CDF results in the final state with a single charged lepton. The combination of the CDF measurements of the inclusive A tt FB in both final states yields A tt FB = 0.160 ± 0.045, which is consistent with the SM predictions. We also measure the differential asymmetry as a function of ∆y. A linear fit to A tt FB (|∆y|), assuming zero asymmetry at ∆y = 0, yields a slope of α = 0.14 ± 0.15, consistent with the SM prediction and the previous CDF determination in the final state with a single charged lepton. The combined slope of A tt FB (|∆y|) in the two final states is α = 0.227 ± 0.057, which is 2.0σ larger than the SM prediction. * Deceased † With visitors from
