چکیده

The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of sqrt[s]=1.96  TeV. We report the results of combinations of the inclusive asymmetries and their differential dependencies on relevant kinematic quantities. The combined inclusive asymmetry is A_{FB}^{tt[over ¯]}=0.128±0.025. The combined inclusive and differential asymmetries are consistent with recent standard model predictions.

Forward-backward asymmetries in top-antitop quark production at the Tevatron

We present the combined results on inclusive forward-backward asymmetries in the production of top-antitop quark pairs and their decay leptons. The analysis is based on measurements by the CDF and D0 experiments at the Fermilab pp Tevatron collider using all the data collected at √ s = 1.96 TeV. The measured asymmetries are in agreement with standard model predictions.

Axigluon signatures at hadron colliders

Axigluons are colored heavy neutral gauge boson that are predicted by some theories. The most important model-independent manifestation of axigluons is the generation of a forward–backward asymmetry in top-antitop quark production at pp̄ collisions which originates from the charge asymmetry. We update our previous analysis for the inclusive QCD induced forward–backward asymmetry and define a new...

Improving the Top Quark Forward-Backward Asymmetry Measurement at the LHC

At the LHC, top quark pairs are dominantly produced from gluons, making it difficult to measure the top quark forward-backward asymmetry. To improve the asymmetry measurement, we study variables that can distinguish between top quarks produced from quarks and those from gluons: the invariant mass of the top pair, the rapidity of the top-antitop system in the lab frame, the rapidity of the top q...

Measurement of the Forward-Backward Charge Asymmetry in Top-Quark Pair Production in Proton-Antiproton Collisions at DØ

A measurement of the forward-backward charge asymmetry in top-antitop (tt̄) pair production in proton-antiproton (pp̄) collisions is presented. The asymmetry is measured for different jet multiplicities in the lepton+jets final state on 0.9 fb−1 of data collected by the DØ experiment at the Fermilab Tevatron Collider. The result is sensitive to new physics, which is demonstrated by setting an upp...

Hadronic top-quark pair production in association with a hard jet at next-to-leading order QCD: Phenomenological studies for the Tevatron and the LHC

We report on the calculation of the next-to-leading order QCD corrections to the production of top–antitop-quark pairs in association with a hard jet at the Tevatron and at the LHC. Results for integrated and differential cross sections are presented. We find a significant reduction of the scale dependence. In most cases the corrections are below 20% indicating that the perturbative expansion i...

Measurement of the forward-backward charge asymmetry in top quark production in proton-antiproton collisions at 1.96 TeV

We report on the D0 measurement of the top-antitop charge production asymmetry based on 5.4 f b −1 of data. Asymmetry dependence on the invariant mass of the top-antitop system, its transverse momentum, as well as the number of extra jets is discussed.
