Abstract
The presented results on top quark properties include measurements of the top quark pair charge asymmetry, the top quark polarization in pair production and single top production, the W helicity in top quark decays. Results of spin correlation in top quark pairs are presented and interpreted in terms of the Standard Model (SM) predicted values. The cross section of tt events produced in association with a W, Z boson or a photon is also presented. The results are compared with predictions from the standard model as well as new physics models.
