Abstract: (arXiv)

We present results from a measurement of double diffraction dissociation in

\bar pp

collisions at the Fermilab Tevatron collider. The production cross section for events with a central pseudorapidity gap of width

\Delta\eta^0>3

(overlapping

\eta=0

) is found to be

4.43\pm 0.02{(stat)}{\pm 1.18}{(syst) mb}

[

3.42\pm 0.01{(stat)}{\pm 1.09}{(syst) mb}

] at

\sqrt{s}=1800

[630] GeV. Our results are compared with previous measurements and with predictions based on Regge theory and factorization.
