Charge Asymmetry of Heavy Quarks at Hadron Colliders
نویسنده
چکیده
A sizeable diierence in the diierential production cross section of top and antitop quarks, respectively, is predicted for hadronically produced heavy quarks. It is of order s and arises from the interference between charge odd and even amplitudes respectively. For the TEVATRON it amounts up to 15% for the diierential distribution in suitable chosen kinematical regions. The resulting integrated forward-backward asymmetry of 4{5% could be measured in the next round of experiments. At the LHC the asymmetry can be studied by selecting appropriately chosen kine-matical regions. Furthermore, a slight preference at LHC for centrally produced antitop is predicted, with top quarks more abundant at large positive and negative rapidities.

Massive color-octet bosons and the charge asymmetries of top quarks at hadron colliders
Several models predict the existence of heavy colored resonances decaying to top quarks in the TeV energy range that might be discovered at the LHC. In some of those models, moreover, a sizable charge asymmetry of top versus antitop quarks might be generated. The detection of these exotic resonances, however, requires selecting data samples where the top and the antitop quarks are highly booste...
متن کاملCharge asymmetries of top quarks: a window to new physics at hadron colliders
Abstract. With the next start of LHC, a huge production of top quarks is expected. There are several models that predict the existence of heavy colored resonances decaying to top quarks in the TeV energy range. A peak in the differential cross section could reveal the existence of such a resonance, but this is experimentally challenging, because it requires selecting data samples where top and ...
متن کاملCharge asymmetry in hadroproduction of heavy quarks
A sizeable difference in the differential production cross section of top and antitop quarks, respectively, is predicted for hadronically produced heavy quarks. It is of order αs and arises from the interference between charge odd and even amplitudes respectively. For the TEVATRON it amounts to approximately 5−10% in the region where the cross section is large and could therefore be measured in...
متن کاملAxigluon 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...
متن کاملOn CP violation and the measurement of the dimuon charge asymmetry at hadron colliders
B factories measure the CP violation parameter of BB̄ mixing and decay. Hadron colliders measure the dimuon charge asymmetry of an admixture of B hadrons. In this note we discuss a subtle point on how the CP violation parameter of B s B̄ 0 s mixing and decay can be extracted from these measurements.
