“…These predictions are different from the NLO SM calculation in Ref. [4] since the simulation does not account for the electroweak corrections [24]. We studied a large number of beyond-SM scenarios with axigluons of a wide variety of masses (200-2000 GeV=c 2 ) and different couplings to the quarks using MADGRAPH [25].…”

We measure the inclusive forward-backward asymmetry of the charged-lepton pseudorapidities from top-quark pairs produced in proton-antiproton collisions and decaying to final states that contain two charged leptons (electrons or muons). The data are collected with the Collider Detector at Fermilab and correspond to an integrated luminosity of 9.1 fb(-1). We measure the leptonic forward-backward asymmetry, A(FB)(l), to be 0.072 +/- 0.060 and the leptonic pair forward-backward asymmetry, A(FB)(ll), to be 0.076 +/- 0.082. The measured values can be compared with the standard model predictions of A(FB)(l) = 0.038 +/- 0.003 and A(FB)(ll) 0.048 +/- 0.004, respectively. Additionally, we combine the A(FB)(l) result with a previous determination from a final state with a single lepton and hadronic jets and obtain A(FB)(l) 0.090(-0.026)(+0.028)

“…The 5 fb −1 results have stimulated new theoretical work, both within and outside the context of the SM. The SM calculation has been improved by calculations of electroweak processes that contribute to the asymmetry, studies of the choice of renormalization scale, and progress on a next-to-next-to-leading order (NNLO) calculation of the asymmetry [5][6][7][8][9]. The new calculations result in a small increase in the expected asymmetry, but not enough to resolve the tension with observation.…”

“…[2]. An improved NLO Monte Carlo generator is used to describe the predicted tt signal, and we also add small corrections reflecting new results on the electroweak contributions to the asymmetry [5][6][7]. Finally, parton-level shape corrections utilize an improved algorithm which yields binned parton-level measurements of the rapidity and mass dependence of the asymmetry.…”

We present new measurements of the inclusive forward-backward tt production asymmetry, AFB, and its dependence on several properties of the tt system. The measurements are performed with the full Tevatron data set recorded with the CDF II detector during pp collisions at √ s = 1.96 TeV, corresponding to an integrated luminosity of 9.4 fb −1 . We measure the asymmetry using the rapidity difference ∆y = yt − yt. Parton-level results are derived, yielding an inclusive asymmetry of 0.164 ± 0.047 (stat + syst). We establish an approximately linear dependence of AFB on the top-quark pair mass M tt and the rapidity difference |∆y| at detector and parton levels. Assuming the standard model, the probabilities to observe the measured values or larger for the detector-level dependencies are 7.4 × 10 −3 and 2.2 × 10 −3 for M tt and |∆y| respectively. Lastly, we study the dependence of the asymmetry on the transverse momentum of the tt system at the detector level. These results are consistent with previous lower-precision measurements and provide additional quantification of the functional dependencies of the asymmetry.

“…In recent years, the values of the forward-backward asymmetry (A FB ) of top-quark-pair production measured at the Tevatron proton-antiproton collider at Fermilab have been consistently larger [1] than those predicted by the standard model (SM) [2][3][4][5][6][7]. Further study of this phenomenon has led to a number of proposed extensions of the SM [8].…”

We measure the particle-level forward-backward production asymmetry in bb pairs with masses (m bb ) larger than 150 GeV=c 2 , using events with hadronic jets and employing jet charge to distinguish b fromb. The measurement uses 9.5 fb −1 of pp collisions at a center-of-mass energy of 1.96 TeV recorded by the CDF II detector. The asymmetry as a function of m bb is consistent with zero, as well as with the predictions of the standard model. The measurement disfavors a simple model including an axigluon with a mass of 200 GeV=c 2 , whereas a model containing a heavier 345 GeV=c 2 axigluon is not excluded.
