Abstract: Results presented at the DIS97 workshop by the H1, ZEUS and E665 collaborations on processes yielding large rapidity gaps and energetic leading baryons are reviewed. A consistent picture begins to emerge in which diffractive processes dominate when the fractional longitudinal momentum loss at the baryon vertex xP is small, with substantial contributions from other processes as xP increases. The diffractive mechanism in the deep-inelastic regime is found, both from inclusive measurements and final state studies, to involve the exchange of a gluon carrying a large fraction of the exchange momentum. Vector meson results show with increasing precision the transition from soft to hard production mechanisms.
