Abstract
Cross section measurements of top quark production in association with a vector boson in proton-proton collisions at at the CERN LHC provide an important probe of the electroweak top quark couplings. In this contribution, recent results of the ATLAS and CMS Collaborations for the measurement of top quark pair and single top quark production in association with a photon or a Z boson are presented. Both inclusive and differential cross section measurements are performed, and the results are compared to state-of-the-art predictions in the standard model of particle physics.
