Top quark mass measurement in the electron+jets decay channel using the Matrix Element Method

Guillaume Garcia (2015)
abstract
The work described in this thesis concerns the analysis of proton-proton collisions that occurred in the course of the year 2012 at a center of mass energy of 8 TeV. Data recorded by the Compact Muon Solenoid at CERN, were filtered in order to isolate collisions giving rise to a top anti-top quark pair. These quarks decay into an electron and four jets. For a recorded luminosity 19.8 fb-1, 8898 events were analyzed after a very tight selection. The analysis was performed with the Matrix Element Method, one of the most accurate methods for a given set of events. This selected data is examined for an event-by-event basis and maximum use of the event kinematics is made. The method is very flexible in the sense it can test any theoretical model, while taking into account all possible experimental effects through systematic uncertainties. This analysis led to a top quark mass measurement of 170.94 ± 2:22 GeV / c2.
