Neutrino oscillation is a fundamental concept in particle physics that describes the behavior of neutrinos in a quantum-mechanical context. Neutrinos are elementary particles that are produced in the cosmos, such as through radioactive decays or high-energy collisions. They have a tiny mass and interact weakly with matter, making them difficult to detect and study.

Neutrinos are known to have three flavors: electron, muon, and tau. These flavors correspond to different combinations of quantum numbers that neutrinos can possess. In a vacuum, neutrinos are stable and do not change their flavor. However, when neutrinos interact with matter or pass through a medium, they can undergo a process called neutrino oscillation.

Neutrino oscillation is a quantum-mechanical phenomenon where a neutrino changes its flavor as it travels through space. This change occurs because neutrinos have mass and can mix with one another, allowing them to change their flavor. The probability of a neutrino changing its flavor depends on the distance it travels and the energy it possesses.

The discovery of neutrino oscillation was a major breakthrough in particle physics and confirmed the theoretical predictions of Masataka Fukuda and others in the 1950s. Experimental evidence for neutrino oscillation was first obtained in 1998 through the Super-Kamiokande experiment, and has since been consistently confirmed by numerous experiments around the world.
