Comparative overview of differential measurements at ATLAS and CMS.

An overview of the measurements of differential top-quark pair production cross sections in proton-proton collisions at a center of mass energy of 13 TeV at the Large Hadron Collider using the ATLAS and CMS detectors is presented. Differential measurements obtained with respect to kinematic distributions of the top quark and $t\bar{t}$ system, performed in different channels are discussed, with particular attention to the differences and similarities on the techniques employed and the results obtained from the two experiments. These measurements probe our understanding of top quark production up to the TeV scale and, in general, show good agreement with the standard model expectations.
