The subject of this thesis is the measurement of the rate at which a top-antitop quark pair is produced in pp collisions at a center of mass energy of ps = 1:96 TeV. The data are collected with the D detector, a multi-purpose detector operating at the Fermilab Tevatron collider during Run II. A measurement of the top quark pair (t$$\bar{t}$$) production cross section ( σ_t$$\bar{t}$$) in p$$\bar{p}$$ collisions at a center of mass energy of 1.96 TeV is presented. The measurement is based on data recorded by the D0 Detector at the Fermilab Tevatron Collider, and preselected in the e+jets (366 pb^-1) and μ+jets (363 pb^-1) channels. The cross section is extracted by applying a lifetime-tagging technique to the data, and yields σ_t$$\bar{t}$$ = 6.96$$+1.07\atop{-0.98}$$(stat + syst) ± 0.45(lumi) pb; for a top quark mass m_t =175 GeV, in good agreement with the Standard Model prediction.
