sterile neutrino models

Sterile neutrinos are hypothetical particles that extend beyond the known types of neutrinos in the Standard Model of particle physics. Unlike regular neutrinos, which interact through weak forces, sterile neutrinos do not interact with matter at all, making them "sterile." They could help explain phenomena like dark matter or neutrino masses, suggesting that there might be more to the universe than we can currently observe. Researchers explore sterile neutrinos to understand fundamental questions about the universe's composition and the nature of particles that govern its behavior.
