摘要：
Precise measurements of top quark couplings are presented. The measurements cover the single top tW cross section, the top-quark branching-fraction ratio R=B(t -> Wb)/B(t -> Wq) and the CKM matrix element V-tb from the single top cross sections. Top quark polarisation in the t-channel single-top quark production and dilepton t (t) over bar, and W-helicity fraction measurements along with searches of top quark anomalous couplings in lepton plus jet channel are also presented. Finally measurements of top quark pair production in association with a W or Z boson or a photon are presented.
