Published online: 26 November 2013
We present different measurements of the top quark properties in production and decay. The measurements are performed using the LHC proton-proton (pp) collisions at 7 TeV and 8 TeV center-of-mass energies collected by the CMS detector during 2011 and 2012 runs, respectively. The study of production properties consists of charge asymmetry, 
spin correlation and the vector boson associated production of 
. The top quark properties in decay are studied via the measurement of the b-quark content, R = ℬ(t → Wb)/ℬ(t → Wq), the top quark charge, the FCNC process of t → Zq and the W-helicity fractions. The results of the last measurement are used to set limits on the tWb anomalous couplings. The W-helicity fractions are measured in the electroweakly produced (single-) top quarks, too.
