Gluon bremsstrahlung, q→Gq, and quark pair production from gluons, laggy, in deep inelastic reactions is investigated in the Breit frame (moving along Q in the laboratory). These QCD effects diminish the overall forward momentum. There are also events with a single large p⊥ forward jet. One spectacular class of events is predicted in which no forward going hadrons emerge, in the Breit frame. These effects are not mimicked by nonperturbative (limited p⊥) parton jets at large but attainable Q2.
