Top quark pair production and decay at hadron colliders
In ongoing and upcoming hadron collider experiments, top quark physics will play an important rôle in testing the Standard Model and its possible extensions. In this work we present analytic results for the differential cross sections of top quark pair production in hadronic collisions at next-to-leading order in the QCD coupling, keeping the full dependence on the spins of the top quarks. Thes...
متن کاملCP Violation in Top Quark Pair Production at Hadron Colliders
CP violating effects in top quark pair production at the future 2 TeV pp̄ Tevatron and 14 TeV pp LHC colliders are investigated. We study three kinds of CP violating sources: the supersymmetric CP-odd phase of the stop trilinear soft breaking term: arg(At), the CP-odd parameter in two-Higgs doublet extensions of the standard model(2HDM), and the model-independent top quark chromoelectric dipole ...
متن کاملTop Quark Pair Production and Decay including Spin Effects at Hadron Colliders: Predictions at NLO QCD
Top quark-antiquark (tt̄) pairs will be produced copiously at the Tevatron collider and in huge numbers at the LHC. This will make possible detailed investigations of the properties and interactions of this quark flavor. The analysis and interpretation of future data requires precise predictions of the hadronic production of tt̄ pairs and of their subsequent decays. In this talk the reactions pp̄,...
متن کاملAngular correlations in top quark pair production and decay at hadron colliders.
We show how to observe sizable angular correlations between the decay products of the top quark and those of the anti-top quark in top quark pair production and decay at hadron colliders. These correlations result from the large asymmetry in the rate for producing like-spin versus unlike-spin top quark pairs provided the appropriate spin axes are used. The effects of new physics at production o...
متن کاملSingle-top-quark production at hadron colliders
Single-top-quark production probes the charged-current weak interaction of the top quark, and provides a direct measurement of the CKM matrix element Vtb. We perform two independent analyses to quantify the accuracy with which the W -gluon fusion (gq → tb̄q) and qq̄ → tb̄ signals can be extracted from the backgrounds at both the Tevatron and the LHC. Although perturbation theory breaks down at low...
