Highlight of top quark properties

The top quark is the heaviest known elementary particle and plays a special role in the dynamics of fundamental interactions. Since its discovery at the Tevatron, several of its properties have been measured by the Tevatron experiments (CDF and DZERO). However, thanks to its unprecedentedly large production rate at the LHC a new level of precision in these measurements has been achieved by the LHC experiments (ATLAS and CMS). The latest LHC measurements of the top quark mass, total decay width, top-antitop spin correlations, and charge asymmetry are presented in this contribution. In addition, the results from the W-boson helicity measurement are presented.
