Abstract

In pp̄ collisions at s=1.8 TeV we find jet events with a rapidity gap topology. The number of hadrons in the rapidity interval ΔηD between leading-jet cones was sampled by charged tracks with PT>400 MeV/c. We find excess trackless events beyond that expected in a smooth multiplicity distribution. In a control region outside ΔηD we see no excess. For ΔηD>0.8, the fraction of excess trackless events, consistent with estimates based on exchange of color-singlet digluons, is R(gap)=σjet(gap) σjet=0.0085±0.0012(stat)-0.0012+0.0024(syst). © 1995 The American Physical Society.
