Neutrino production of hadrons at low energy and in the small Q^2 region release_x5etw4veojck3nygyschikaaxe

Released as a report .



We use PCAC in the small Q^2 region in order to calculate the Adler sum rule and the production of hadrons in the low energy region where resonances dominate. We find very good agreement with the sum rule and with the computed cross sections. We find a value C_5^A(0) close to the Goldberger-Treiman prediction. The formalism is general and can be applied to other reactions shedding light into the dynamical transition from resonances to deep inelastic scattering.
