Abstract
We use a model for baryons that links the constituent structure to the deep inelastic (current) properties. The approach consists in a laboratory partonic description (based on a model of hadron structure), to which a low momentum scaleQ 0 is adscribed, which is evolved to high momenta by means of the renormalization group. A generalization of the model by means of the hadronic quark cluster decomposition, provides a description of the structure functions of nuclei and is the starting point to study the effects that the antisymmetrization at the quark level has on the structure function of a model deuteron. The analysis contains conventional and high momentum partonic components. We next study quark Pauli blocking scenarios by including exotic delta nuclei in our analysis. By assuming that nuclei are composed of quasi-deuteron clusters, i.e., the deuteron parameters are density dependent, we analyze these effects on the structure functions of heavier nuclei.
