Muon neutrinos are tiny, nearly massless particles that are part of the Standard Model of particle physics. They are produced when muons, which are heavier cousins of electrons, decay. Muon neutrinos interact very weakly with matter, making them difficult to detect, but they play a crucial role in understanding the universe and the fundamental forces that govern it. These neutrinos are one of three types, or "flavors," of neutrinos, the others being electron neutrinos and tau neutrinos. Scientists study muon neutrinos using large detectors, often located underground, to explore their properties and how they oscillate between different flavors. This research helps deepen our understanding of particle physics and the nature of the universe.
