| contents | For standard model (SM) processes involving top quarks, such as top quark-antiquark pair production or single top quark production, the theoretical predictions depend on fundamental parameters of the SM like the top quark mass. Using the large data sample collected at the CERN LHC in the second data-taking period by the ATLAS and CMS experiments, these parameters can be extracted in experimental measurements with high precision. Furthermore, properties of the production processes such as quark polarization or asymmetries can be measured. Exploiting the large luminosity of the data set, new kinematic regimes and methods are explored, as for events in which the top quarks have a very large transverse momentum. In these proceedings, recent measurements of SM parameters and top quark properties are presented. Individual results are also interpreted in terms of effective field theory extensions of the SM. |
