Abstract
A summary of the latest results on inclusive and differential $\mathrm{t}\bar{\mathrm{t}}$ cross sections by CMS is presented. Several new differential cross section measurements have been performed by CMS using an amount of 35.9 fb$^{-1}$ of data collected in 2016. The studies include differential cross section measurements as a function of the $\mathrm{t}\bar{\mathrm{t}}$ system, the top quarks, its decay products and global event variables. Double-differential cross sections are also explored. Investigations on the jet substructure in $\mathrm{t}\bar{\mathrm{t}}$ events are also presented. Finally, the first measurement of the underlying event in $\mathrm{t}\bar{\mathrm{t}}$ events is summarized. All these new measurements provide excellent information about the agreement between the observations and different generators and theoretical parametrizations used in $\mathrm{t}\bar{\mathrm{t}}$ modeling.
