Query: Dispersion relation analysis of the neutral kaon regeneration amplitude
  in carbon   We apply a forward dispersion relation to the regeneration amplitude for kaon
scattering on 12C using all available data. The CPLEAR data at low energies
allow the determination of the net contribution from the subthreshold region
which turns out to be much smaller than earlier evaluations, solving a long
standing puzzle.
