Single Top Quark Production via FCNC Couplings at Hadron Colliders
نویسندگان
چکیده
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 distinguished by a comparision of the single top signal with the direct top and top decay signals for these couplings.

FCNC top quark production via anomalous tqV couplings beyond leading order
We calculate flavor-changing neutral-current (FCNC) processes involving top-quark production via anomalous tqV couplings at the Tevatron and HERA colliders. We cover the FCNC processes pp̄ → tZ, pp̄ → tγ, pp̄ → tt, and ep → et. We go beyond leading order and include the effects of soft-gluon corrections through next-to-next-to-leading order. We demonstrate the stabilisation of the cross section wi...
متن کاملAnomalous tqV couplings and FCNC top quark production
We discuss FCNC top quark production via anomalous tqV couplings at the Tevatron and HERA colliders. We calculate higher-order soft-gluon corrections to such processes and demonstrate the stabilization of the cross section when these corrections are included.

متن کاملProbing Electroweak Top Quark Couplings at Hadron and Lepton Colliders
Although the top quark was discovered almost ten years ago [1,2], many of its properties are still only poorly known [3]. In particular, the couplings of the top quark to the electroweak (EW) gauge bosons have not yet been directly measured. Current data provide only weak constraints on the couplings of the top quark with the EW gauge bosons, except for the ttZ vector and axial vector couplings...
متن کاملZt and γt production via top flavour - changing neutral couplings at the Fermilab Tevatron
Associated single top production with a Z boson or a photon at large hadron colliders provides a precise determination of top flavour-changing neutral couplings. The best way to measure these couplings with the up quark at Tevatron is to search for events with three jets and missing energy or events with a pho-ton, a charged lepton, a jet and missing energy. The other significant decay channels...
