Neutrino Oscillation Explained: How Neutrinos Change Flavors #1434859 (License: Personal Use)

This diagram depicts neutrino oscillation, a quantum mechanical process where neutrinos switch between three flavor eigenstates-electron (νₑ), muon (ν_μ), and tau (ν_τ)-as they propagate through space. The orange and blue bidirectional arrows represent probability amplitudes for transitions governed by mixing angles and mass differences in the PMNS matrix. This phenomenon confirms that neutrinos have non-zero mass, contradicting the original Standard Model assumption.

Used in educational physics articles, university lecture slides, and science communication pages explaining particle physics or solar neutrino problems; matches user intent to understand fundamental particle behavior and experimental evidence for neutrino mass.
