Abstract: The nature of neutrino, whether it is a Dirac type or Majorana type, may be comprehensively probed using their quantum statistical properties. If neutrino is a Majorana fermion, then by definition it is identical and indistinguishable from the corresponding antineutrino. When a Majorana neutrino and antineutrino are pair produced, the corresponding state has to obey Pauli principle unlike in the Dirac case. We use this property to distinguish between the two cases using the process B0 → μ？ μ+ νμ ˉνμ. I also give comments on possible use of J/psi -> mu mu nu nu, which can be directly probed at BES III.
