Abstract

A combined search for standard model four-top-quark production in the single\nlepton plus jets and dilepton channels will be presented. The analysis utilises\nthe 2015 dataset recorded by the CMS experiment at sqrt(s) = 13 TeV which\ncorresponds to an integrated luminosity of 2.6 fb-1. A scheme based on a\nboosted decision tree algorithm is used to select signal and suppress\nbackgrounds. An upper limit on the cross section of four-top-quark production\nwill be presented.\n
