Developments in the search for 4 top production at CMS

Abstract

The production of t￣tt￣t in pp collisions has been studied in CMS at √ s = 13 TeV. We develop an analysis aimed to search for t￣tt￣t production. The analysis developed uses regions with two same-sign and three leptons in the final state. We optimise the selection based on the number of b-tagged jets and the total transverse momentum. The sensitivity of the designed analysis is estimated using simulations, achieving an expected significance of 2.8 standard deviations.
