Dirac Neutrino

A Dirac neutrino is a type of neutrino, a tiny, nearly massless particle that interacts very weakly with matter. In physics, particles like neutrinos can be their own antiparticles or have distinct antiparticles. If neutrinos are Dirac particles, they have separate neutrino and antineutrino forms, like electrons and positrons. This distinction affects how neutrinos behave and decay. Detecting whether neutrinos are Dirac or Majorana particles helps scientists understand fundamental physics and the nature of matter. The key idea is that Dirac neutrinos have a clear particle-antiparticle relationship, maintained by specific conservation laws.
