Neutrino oscillation is a quantum mechanical phenomenon where a neutrino changes its flavor as it propagates through space, providing evidence for neutrino mass. This discovery has profound implications for the Standard Model of particle physics, indicating that it is incomplete and requiring extensions to incorporate neutrino masses.

quantum mechanical phenomenon

Neutrino flavor refers to the identity of a neutrino, which can change as it travels through space, a phenomenon known as neutrino oscillation. This characteristic is crucial for understanding the fundamental properties of neutrinos and their role in the universe, as it implies that neutrinos have mass, contrary to what was once believed.

Neutrino mass is a fundamental aspect of particle physics that challenges the Standard Model, as neutrinos were originally thought to be massless. The discovery of neutrino oscillations, where neutrinos change flavors, implies that they have mass, leading to significant implications for cosmology and the understanding of the universe's evolution.

The Standard Model of Particle Physics is a well-established theory that describes three of the four known fundamental forces in the universe and classifies all known subatomic particles. It successfully explains electromagnetic, weak, and strong nuclear interactions but does not incorporate gravity or account for dark matter and dark energy.
