Summary
Diffractive neutrino-production of pions at low virtuality Q^2 is dominated by the axial current, which is partially conserved. PCAC in the form of the Adler relation connects diffractive diagonal and off-diagonal transitions in the axial channel. This is why high-energy neutrino interactions are usually considered as a
sensitive test of the PCAC hypothesis. Final state interactions, known as absorption corrections, lead to a dramatic breakdown of the Adler relation.
