Regge-dual model of the proton structure function F2

In a series of papers, a two-dimensionally dual model combining both the resonance-Regge and quark-hadron dualities was developed. Here, we present fits to the recently measured inclusive electron-proton cross section in the nucleon resonance region, as performed with the CLAS detector at JLab. The helicity structure of the scattering amplitudes is discussed.
