Description
- Abstract:
- This thesis presents a measurement of the mass of the top quark. The top quarks are produced through proton-antiproton collisions with $\sqrt{s}$=1.96 TeV at the Fermilab Tevatron collider using the D\O\ detector. The method employed for the measurement is called the Ideogram Technique. The events used in the measurement are selected such that the top quark decay signatures (as seen in the detector) are at least one lepton (electron or muon), four or more jets with at least one of them tagged as originating from a b-quark and missing transverse momentum. These events are then fitted using a kinematic fitter. The event-by-event likelihood is calculated using templates that depend on the kinematically reconstructed top quark mass. The events are weighted by their probability to be signal or background, using topological information. The measurement of the top quark mass is 175.7$\pm$1.98 $GeV/c^{2}$.
