Electron neutrinos are tiny, nearly massless particles that are part of the family of neutrinos. They are produced in various nuclear reactions, such as those occurring in the sun during the process of nuclear fusion. Electron neutrinos interact very weakly with matter, which makes them difficult to detect, but they play a crucial role in understanding fundamental physics and the workings of the universe. These neutrinos are associated with the electron, one of the basic building blocks of matter. When a neutron decays, it transforms into a proton, emitting an electron and an electron neutrino in the process. Studying electron neutrinos helps scientists learn more about particle physics and the forces that govern the behavior of particles in the universe.
