摘要
The large mass of the top quark, close to the electroweak symmetry-breaking scale, makes it a good candidate for probing physics beyond the Standard Model, including possible anomalous couplings. D0 has made measurements of single top quark production using 5.4 fb − 1 of integrated luminosity. The data are examined to study the Lorentz structure of the Wtb coupling. It is found that the data prefer the left-handed vector coupling and set upper limits on the anomalous couplings.
