  Neutrino and anti-neutrino induced single-charm production are particularly
interesting to study the strange-quark parton distribution function and the
threshold effect in the cross-section, associated with the heavy quark
production. Over the past 30 years, many experiments have carried out these
studies with complementary techniques: calorimetry, bubble chambers and nuclear
emulsions. In this paper, we review these data and combine them statistically
to extract a world averaged single-charm production cross-section for both
neutrino and anti-neutrino.
