Top-Quark Decay Via the Anomalous Coupling t̄cγ at Hadron Colliders

We determine the constraints on the anomalous top-quark coupling associated with the flavor-changing neutral current vertex t̄cγ from the limits on the b-quark rare decay b → sγ and non-standard top-quark decays. Based on these constraints, we discuss the experimental observability of the rare decay mode t → cγ, both at the Fermilab Tevatron with a luminosity-upgrade and at the LHC.

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...

Single Top Quark Production via FCNC Couplings at Hadron Colliders

We calculate single top–quark production at hadron colliders via the chromo–magnetic flavor–changing neutral current couplings t̄cg and t̄ug. We find that the strength for the anomalous t̄cg (t̄ug) coupling may be probed to κc/Λ = 0.092 TeV −1 (κu/Λ = 0.026 TeV ) at the Tevatron with 2 fb of data and κc/Λ = 0.013 TeV −1 (κu/Λ = 0.0061 TeV) at the LHC with 10 fb of data. The two couplings may be dis...

Top-Quark Decay Via Flavor-Changing Neutral Currents at Hadron Colliders

We study low energy experimental constraints on an anomalous top-quark coupling associated with the flavor-changing neutral current vertex Zt̄c. In view of these constraints, we discuss the experimental observability of the induced rare decay mode t → Zc, both at the Fermilab Tevatron (with the Main Injector or a luminosity-upgrade) and at the LHC.

Top Quark Physics At Hadron Colliders

I summarize here the latest top quark physics results from the ATLAS, CDF, CMS and D0 collaborations , first discussing the top quark production and then some of the latest top quark property measurements. These results are based on up to 5.4 fb −1 at the Tevatron and up to 1.10 fb −1 at the LHC.
