Anomalous Top Quark Couplings at the Future Linear Colliders ∗
In terms of an effective Lagrangian we investigate the possibilities of probing anomalous top quark couplings, t ¯ tH, γt ¯ t, Zt ¯ t and tW b at the future linear colliders. It is found that at a linear collider with a c. m. energy √ s ∼ 0.5 − 1.5 TeV and a high luminosity of 10 − 1000 fb −1 , e + e − → t ¯ tH is an ideal process in probing anomalous t ¯ tH couplings. We also study in detail t...
متن کاملTop-quark spin correlation at Linear Colliders with anomalous couplings
We investigate the feasibility of probing anomalous top-quark couplings of Wtb, Ztt̄, and γtt̄ in terms of an effective Lagrangian with dimension-six operators at future e+e− linear colliders with a c. m. energy √ s ∼ 500 − 800 GeV. We first examine the constraints on these anomalous couplings from the Z → bb̄ data at LEP I and from unitarity considerations. We then consider in detail the effects ...
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 کاملTop - Quark Couplings at Lepton and Photon Colliders ∗
The Standard Model (SM) has provided a remarkably successful description of almost all available data involving the strong and electroweak interactions. In particular, the discovery of the top-quark at the Tevatron with a mass mt = 173.5± 5.2 GeV, close to that anticipated by fits to precision electroweak data is a great triumph. Nonetheless, the SM leaves many fundamental questions unanswered,...
