Quark-Hadron Duality in the Rein-Sehgal Model

The quark-hadron duality in neutrino interactions is considered. Resonance production is described by the Rein-Sehgal model and its contribution to the overall inclusive cross section is evaluated by means of 1-pion functions. The duality appears to be present on the approximate level. In the NC reactions the deviations from duality are smaller then in the CC channels. The impact of the corrections to the PDFs proposed by Bodek-Yang is also investigated. The hypothesis of two-component duality is verified with the negative conclusion: no relation is found between contributions from non-resonant background of the Rein-Sehgal model and from the sea quarks
