Abstract

We review recent measurements of the properties of the top quark by the CDF and D0 experiments: the mass and decay width of the top quark, the ratio $R=\btwb/\btwq$, the total production cross section of \ttbar\ pairs, the helicity of the $W$ boson, anomalous couplings at the $Wtb$ vertex, the asymmetry of $\ttbar$ production due to the colour charge, and the first study of the top quark polarisation. The measurements are performed using data samples of up to 8.7 \fb\ acquired by the CDF and D0 experiments in Run II of the Fermilab Tevatron $p\bar p$ collider at a centre-of-mass energy of $\sqrt s=1.96 \TeV$.
