SUMMARY

Neutrinos and anti-neutrinos are both leptonic particles characterized by their mass, spin, and charge. When neutrinos interact with matter, they produce leptons such as electrons, muons, or tau particles, while anti-neutrinos yield corresponding anti-leptons like positrons or anti-muons. Current experimental evidence does not rule out the possibility of Majorana neutrinos, which suggests that neutrinos and anti-neutrinos could be identical. This discussion highlights the fundamental differences in interactions and potential identities of these particles.

PREREQUISITES

  • Study the Standard Model of particle physics for context on leptons
  • Investigate the role of neutrinos in astrophysics and cosmology
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the fundamental properties of matter and the universe.

Given the properties of this leptons particles (mass, spin, charge) and the fact (not sure at all) that neutrinos and anti-neutrinos have no smaller constituents, I was wondering what are the differences between this particles.

 
Physics news on Phys.org
When a neutrino interacts with something, you get a lepton out (e-, μ- or τ-). When an antineutrino interacts with something, you get an anti-lepton out (e+, μ+ or τ+).
 
Afaik we can't rule out a Majorana neutrino experimentally, i.e. it could be that neutrino and anti-neutrino are identical.
