People say that if neutrinos are Majorana particles, they are "identical to their anti particle". But anti neutrinos are obviously different from neutrinos. They produce anti-leptons rather than leptons in the scattering process. So the only difference I can image is the helicity, however that is not Lorentz invariant.......
As I understand it, a Majorana neutrino will look like an antineutrino in some reference frames. So, yes, it is the helicity that makes the difference, and, right, it is not Lorentz invariant.
