Query: Diffractive neutrino-production of pions on nuclei: Adler relation
  within the color-dipole description   Effects of coherence in neutrino-production of pions off nuclei are studied
employing the color dipole representation and path integral technique. If the
nucleus remains intact, the process is controlled by the interplay of two
length scales. One is related to the pion mass and is quite long (at low Q^2),
while the other, associated with heavy axial-vector states, is much shorter.
The Adler relation is found to be broken at all energies, but especially
strongly at \nu > 10 GeV, where the cross section is suppressed by a factor
~A^{-1/3}. On the contrary, in a process where the recoil nucleus breaks up
into fragments, the Adler relation turns out to be strongly broken at low
energies, where the cross section is enhanced by a factor ~A^{1/3}, but has a
reasonable accuracy at higher energies, where all the coherence length scales
become long.
