Majorana neutrinos

Majorana neutrinos are a theoretical type of neutrino that is their own antiparticle, meaning they can annihilate with themselves. In physics, neutrinos are very light, neutral particles that interact weakly with matter. If Majorana neutrinos exist, they could help explain why there is more matter than antimatter in the universe. They are named after the Italian physicist Ettore Majorana, who first proposed the idea. Their existence would have significant implications for particle physics and our understanding of the fundamental building blocks of the universe, potentially impacting theories about the origins of mass and the nature of matter itself.
