Abstract
We study the quark and gluon final state in deep inelastic μ-scattering. For a hadron observed at sufficiently large angleθ h with respect to the virtual photon direction, and sufficiently large energy fractionz h , this final state dominates the cross-section. Moreover, at the same time, most events in this regime are due to the fragmentation of the quark. In such cases the position of the gluon in phase space is determined, the quark acting as a trigger for gluon jet detection. We demonstrate that in the rest frame of the final quark and gluon, the gluon is energetic and well separated from quark and target fragments. We study the boost from the lab to this frame, and give expressions for the most probable boost in terms ofθ h andz h . This study should lead to a convenient visualization of the gluon jet.
