Small-x neutrino-hadron structure functions in charged current DIS within the QCD color dipole picture

We present an exploratory QCD analysis of the neutrino structure functions in charged current DIS using the color dipole formalism. The corresponding dipole cross sections are taken from recent phenomenological/theoretical studies in deep inelastic inclusive production. The theoretical predictions are compared to the available experimental results in the small-x region. In particular, the behavior of the structure functions on the boson virtuality and the role played by the nuclear shadowing corrections are investigated. It is demonstrated that small-x neutrino-hadron cross section exhibits geometric scaling property as in lepton-hadron processes.
