| Abstract: | We present results from a measurement of double diffraction dissociation in pp collisions at the Fermilab Tevatron collider. The production cross section for events with a central pseudorapidity gap of width Deltaeta(0)>3 (overlapping eta = 0) is found to be 4.43+/-0.02(stat)+/-1.18(syst) mb 3.42+/-0.01(stat)+/-1.09(syst) mb] at square root of (s) = 1800630] GeV. Our results are compared with previous measurements and with predictions based on Regge theory and factorization. |
