Neutrino mixing is the quantum phenomenon where neutrinos switch between different flavors as they propagate through space, a process that arises due to the mismatch between flavor and mass eigenstates. This behavior provides crucial evidence for neutrino mass and has significant implications for the Standard Model of particle physics and our understanding of the universe's fundamental forces.

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.
