neutrino beam

A neutrino beam is a focused stream of neutrinos—a type of fundamental particle with very little mass and no electric charge—that are generated in particle accelerators or nuclear reactions. Scientists produce these beams by smashing high-energy particles into targets, creating neutrinos as byproducts. Because neutrinos rarely interact with matter, they pass through objects, including the Earth, almost unaffected. Studying neutrino beams helps researchers understand fundamental forces and particles, explore the universe's origins, and answer big questions in physics. They are essential tools for experiments probing the nature of matter and the universe itself.
