Abstract
Due to the weak current non-conservation
the diffractive excitation of charm and strangeness
dominates the longitudinal structure function FL(x,Q2) of
neutrino DIS at small Bjorken x. Based on the color dipole BFKL approach
we report quantitative
predictions for this effect in the kinematical range of the
CCFR/NuTeV experiment. We comment on the relevance of our findings to
experimental tests of PCAC.
