We report a measurement of the fraction of events with a large pseudorapidity gap $\Delta\eta$ within the pseudorapidity region available to the proton dissociation products $X$ in $\bar p+p\to \bar p+X$. For a final state $\bar p$ of fractional momentum loss $\xi_{\bar p}$ and 4-momentum transfer squared $t_{\bar p}$ within …
