Abstract

We present a measurement of the elastic differential cross section dσ( pp-→ pp-)/dt as a function of the four-momentum-transfer squared t. The data sample corresponds to an integrated luminosity of ≈ 31 nb-1 collected with the D0 detector using dedicated Tevatron pp- Collider operating conditions at √s = 1.96 TeV and covers the range 0.26 < │t │ < 1:2 GeV2. For │t│< 0.6 GeV2, dσ/dt is described by an exponential function of the form Ae-b│t│with a slope parameter b = 16.86 ± 0.10(stat) ± 0.20(syst) GeV-2. A change in slope is observed at │t│≈ 0.6 GeV2, followed by a more gradual │t│ dependence with increasing values of │t│.
