Abstract
Latest results on inclusive and differential top quark pair and single top quark production cross sections are presented using proton-proton collision data collected by the CMS experiment. The differential cross sections are measured as a function of various kinematic observables of the top quarks and the jets and leptons of the event final state. The results are confronted with precise theory calculations and used to constrain Standard Model parameters. Measurements are performed also with high pT top quarks, i.e., in boosted regimes.

Report
The work summarize tt cross section for different CMS collision energies. Results at low energy at 5.02 TeV provides another way of testing the consistency of SM prediction with the observation at lower energy. Measurement vis versus production channels like tW, ttγ, ttcc and ttbb are in agreement with SM. I find the content is very well written. I would recommend this paper for publication.
