neutrins

Neutrinos are fundamental subatomic particles with no electric charge and very small mass. They belong to the lepton family, alongside electrons, muons, and taus. Neutrinos are produced in various nuclear processes, including nuclear fusion within stars, radioactive decay, and the explosion of supernovae. They can also be created in particle accelerators.

One of the most remarkable properties of neutrinos is their ability to pass through matter almost unimpeded. They interact very weakly with other particles, meaning they can travel vast distances, even through the Earth, without being stopped. This makes them incredibly difficult to detect.

There are three known types, or "flavors," of neutrinos: the electron neutrino, the muon neutrino, and the tau neutrino. These flavors are associated with their charged lepton partners. A phenomenon known as neutrino oscillation means that neutrinos can change from one flavor to another as they travel. This discovery provided strong evidence that neutrinos have mass, albeit a very small one.

Studying neutrinos offers a unique window into fundamental physics and astrophysics. They carry information from the cores of stars and other extreme cosmic environments that are otherwise inaccessible. Experiments designed to detect neutrinos are often located deep underground or underwater to shield them from other sources of radiation.
