neutrínó

A neutrino is a fundamental subatomic particle that belongs to the lepton family. It has no electric charge and a very small mass, making it extremely difficult to detect. Neutrinos interact only weakly with other matter, primarily through the weak nuclear force and gravity. This weak interaction means that they can travel through vast distances and dense objects, such as stars and planets, without being significantly deflected or absorbed.

There are three known types, or "flavors," of neutrinos: the electron neutrino, the muon neutrino, and the tau neutrino. Each flavor is associated with a corresponding charged lepton. Neutrinos are produced in various nuclear reactions, including those that occur in the Sun, supernovae, and nuclear reactors. They are also created in particle accelerators and cosmic ray interactions.

The study of neutrinos is a significant area of research in particle physics and astrophysics. Experiments are designed to detect neutrinos and study their properties, such as their mass and oscillations, which is the phenomenon where a neutrino of one flavor can change into another flavor as it travels. Understanding neutrinos provides insights into the fundamental forces of nature, the evolution of stars, and the composition of the universe.
