Abstract
We propose models for deep inelastic lepton-hadron scatterings, incorporating the general ideas of the fragmentation picture. Approximate scaling behavior can be accommodated at present values of the momentum transfer. But at larger momentum transfers, significant deviations from scaling are expected. In contrast to the results of the parton model, a scaling behavior for the average multiplicity and the structure functions at fixed multiplicities is not possible, according to the fragmentation picture. We present results of our model regarding the average multiplicity and the structure functions.
