Anti-Neutrinos

The electron neutrino has a corresponding antiparticle, the electron antineutrino (Ī½e), which differs only in that some of its properties have equal magnitude but opposite sign. One open question of particle physics is whether or not neutrinos and anti-neutrinos are the same particle, in which case it would be a Majorana fermion, or whether they are different particles, in which case they would be Dirac fermions.

Source : Wikipedia

Several experiments are underway at research facilities to try to determine whether neutrinos and anti-neutrinos are in fact the same particle, e.g. GERDA, EXO, and SNO+. (see Wikipedia)

As yet there are no firm results.

New research has found that the neutrino has a non-zero mass - but this requires a modification to the Standard Model of particle physics. The non-zero mass also means that neutrinos cannot travel at light-speed as photons do.
