SUMMARY:Measurement of the Three Top Quarks Process with the CMS Detec
 tor at the LHC\, Thesis Defense\, Dylan Teague\, Physics PhD Graduate 
 Student
DESCRIPTION:This thesis presents the first analysis measuring the thre
 e top quark decay process at the Large Hadron    Collider. The measure
 ment was performed on events with two same-sign leptons and three or m
 ore    leptons on data taken by the Compact Muon Solenoid detector dur
 ing the 2016–2018 data taking period corresponding to 137 fb-1 of da
 ta 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 o
 f 28.1 fb. These results were also uses    to reinterpret the data to 
 place limits on possible beyond Standard Model physics models that pre
 dict    enhancements to the three top quark cross-section.
