Diffraction dissociation in collisions at √s=1.8 TeV
Physics Letters B(1993)
摘要
Abstract We have studied single diffraction dissociation ( p p→ p X ) in proton-antiproton collisions at √s=1.8TeV, covering the ranges 3⪅MX⪅200 GeV and 0.05⪅|t|⪅0.11 (GeV/c)2. Parameterizing the production to be of the form dσ ( d t d M 2 X ) = (M 2 X ) −α exp (bt) , we obtain α = 1.13±0.07 and b = 10.5±1.8(GeV/c)−2. The total single diffraction dissociation cross section is 2σSD=8.1±1.7 mb. Comparisons are made to previous lower energy data, and to an earlier measurement by us at the same energy.
