They may also include interference and final state interaction, providing a source for azimuthal asymmetries at HERMES and (especially) $Λ$ polarization at NOMAD. The recent papers by Brodsky, Hwang and Schmidt, and by Gluck and Reya, may be understood in terms of fracture functions.6 Pages, Presented at DIS2002, Kraków, 30.4.--4.5.2002High Energy Physics - Phenomenologytext
