Abstract
We describe the latest results obtained by the CMS Collaboration on top quark spin and polarization properties. The top quark spin asymmetry is measured both targeting single-top quark production in the -channel and single-top quark production in association with a Z boson. Additionally, all the independent coefficients of the spin-dependent part of the top quark-antiquark production density matrix are measured and the results are extrapolated to the High-Luminosity LHC scenario.
