Measurement ofp¯psingle diffraction dissociation at √s=546 and 1800 GeV

Abstract
We report a measurement of the diffraction dissociation differential cross section d2 σSD/dM2dt for p¯pp¯X at √s =546 and 1800 GeV, M2/s<0.2 and 0≤-t≤0.4 GeV2. Our results are compared to theoretical predictions and to extrapolations from experimental results at lower energies.
