Measurements of the top-quark properties in the production and decays of ttbar events at CMS and ATLAS

Abstract

Recent measurements of top-quark properties (excluding the top quark mass) at ATLAS and CMS are discussed. This includes latest updates of measurements of $t\bar{t}$ production asymmetries, spin correlations and $W$ helicity, as well as the polarization and anomalous couplings of the top quark. Furthermore results on the associate production of $W$, $Z$ and $\gamma$ with a $t\bar{t}$ pair are presented. All of these measurements employ the full data set at $\sqrt{s}=7$ or 8 TeV corresponding to an integrated luminosity of $4.7/$fb or $19.7/$fb. The results of all these measurements agree well with their respective Standard Model expectation.
