Double Diffraction Dissociation at the Fermilab Tevatron Collider

We present results from a measurement of double diffraction dissociation in $\overline{p}p$ collisions at the Fermilab Tevatron collider. The production cross section for events with a central pseudorapidity gap of width $\Delta {\eta }^0>3\mathrm{}$ (overlapping $\eta =0\mathrm{}$) is found to be $4.43\pm 0.02\left(\mathrm{stat}\right)\pm 1.18\left(\mathrm{syst}\right)\mathrm{mb}$ [ $3.42\pm 0.01\left(\mathrm{stat}\right)\pm 1.09\left(\mathrm{syst}\right)\mathrm{mb}$] at $\sqrt{s}=1800\mathrm{}\left[630\right]\mathrm{GeV}$. Our results are compared with previous measurements and with predictions based on Regge theory and factorization.
