Neutrino Chiral Oscillations
  A localized wave packet exhibits under certain conditions zitterbewegung. A similar phenomenon occurs for the chirality of a massive particle. In the case of massive neutrinos, since they are detected via the V-A weak charged currents, this oscillation may even explain the ``missing'' solar neutrino experiments. The neutrino remains a mass eigenstate but contains an almost sterile right-handed component. This qualitative discussion opens up a number of interesting physical considerations.
