A comprehensive set of inclusive and differential measurements of top quark pair and single top quark production in association with EWK bosons (W, Z or ɣ) and in association with light, c- and b-jets is presented. The results are compared to theory predictions and re-interpreted as searches for new physics inducing deviations from the standard model predictions. [...]

For the high-luminosity LHC (HL-LHC), CMS will install a completely new silicon tracker. The future tracker will consist of two barrel parts and two endcaps (TEDD), one on each side. [...]

Measurements of top quark properties using data collected by the CMS experiment at 13 TeV are presented. They include direct measurements of properties or extractions using differential cross section measurements. [...]
