- Abstract: This thesis presents the first analysis measuring the three top quark decay process at the Large Hadron Collider. The measurement was performed on events with two same-sign leptons and three or more leptons on data taken by the Compact Muon Solenoid detector during the 2016–2018 data taking period corresponding to 137 fb-1 of data with √𝑠 = 13 TeV. The analysis found the three top process to have an overall significance of 0.182𝜎 and a CLs 95 % upper limit of 28.1 fb. These results were also uses to reinterpret the data to place limits on possible beyond Standard Model physics models that predict enhancements to the three top quark cross-section.
