Query: Mean charged multiplicities in charged-current neutrino scattering on
  hydrogen and deuterium   Available experimental data are analyzed to derive simple parametrizations
for the mean charged-hadron multiplicities in charged-current neutrino and
antineutrino interactions with hydrogen and deuterium targets. The obtained
results can be used in the (anti)neutrino-induced hadronic shower modeling.
