	<mods: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

$GeV/c^{2}$.
