A search for events containing four top quarks (t (t) over bart (t) over bar) is reported from proton-proton collisions recorded by the CMS experiment at root s = 13 TeV and corresponding to an integrated luminosity of 2.6 fb(-1). The analysis considers the single-lepton (e or mu)+jets and the opposite-sign dilepton (mu(+)mu(-),mu +/- e -/+ , or e(+) e(-))+ jets channels. It uses boosted decision trees to combine information on the global event and jet properties to distinguish between t (t) over bart (t) over bar and t (t) over bar production. The number of events observed after all selection requirements is consistent with expectations from background and standard model signal predictions, and an upper limit is set on the cross section fo...
