The analysis described in this dissertation uses the Forward Proton Detectors (FPD) installed at the D0 detector in the Tevatron collider at Fermilab to measure the single diffractive differential cross section (d&sigma/(d|t|)) at sqrt(s ) = 1.96 TeV center of mass energy. The single diffractive events are selected using the D0 central detector and the FPD system and |t| of the forward proton are measured using the FPD system. The analysis presents the measurement of the differential cross section of the single diffractive events as a function of |t| in the range 0.2 < |t| < 1.3 GeV2. The differential cross section measurement is within the theoretical and experimental expectations. The total single diffractive cross section (&sigma_sd ) in the region 0.0 < |t| < 1.3 GeV2 is found to be 9.682 Â± 0.048(stat.) Â± 1.219(syst.) mb.
