The analysis described in this dissertation uses the Forward Proton Detectors(FPD) installed at the DØ detector in Tevatron collider at Fermilab to measure the single diffractive differential cross section dσ/d|t| at √s = 1.96 TeV center of mass energy. The single diffractive events were selected using the DØ central detector and the Forward proton detectors and |t| of the forward protons are measured using the FPD system. The analysis presents the measurement of the differential cross section of the single di ractive 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( σ_sd) in the region 0.0 < |t|< 1.3 GeV² is found to be 9.682 0.048 (stat.) 1.219 (syst.) mb.
