Phenomenology of forward hadrons in deep inelastic scattering: Fracture functions and its [Formula presented] evolution

We analyze recent data on the production of forward neutrons in deep inelastic scattering at DESY HERA in the framework of a perturbative QCD description for semi-inclusive processes, which includes fracture functions. Using a model estimate for the nonperturbative piece of the fragmentation process...
