The structure of the Wtb-vertex can be tested using single top and t¯t events collected at the LHC. The measurement of the t-channel single top quark production cross section by the CMS Collaboration was used to constrain the Vtb CKM matrix element, while the measurements of the helicity fractions of W bosons and angular asymmetries in top quark decays by the ATLAS Collaboration were used to constrain possible new physics contributions to the Wtb-vertex.
