【 摘 要 】

In this contribution, we review some of the properties of the top quark in LHC measurements by the CMS and ATLAS Collaborations using pp collisions at 7 TeV. Firstly, measurements of two intrinsic properties of the top quark are revisited: its charge and branching ratio. Then, the first measurements of associated production of top pairs with electroweak gauge bosons W, Z and photons are presented. Associated production cross-sections provide information on the structure of the electroweak couplings to top quarks. All measurements are consistent with the expectations from the standard model top properties.
