Abstract

We present measurements of the tWb coupling form factors using information from electroweak single top quark production and from the helicity of W bosons from top quark decays in t¯t events. We set upper limits on anomalous tWb coupling form factors using data collected with the D0 detector at the Tevatron p¯p collider corresponding to an integrated luminosity of 5.4 fb−1.
