4. Neutrino OscillationΒΆ

The most amazing thing about neutrinos is that they oscillate. Well, you may have heard it may times in the press, which has been awarded with Noble Prize in Physics for 2015. But, what is it?

The mechanism behind neutrino flavor oscillation is still not fully understood. But what we do know is that the flavor oscillation behaviour voilates the Standard Model, which has been the most robust theory in physics in the last half century. The neutrino has different oscillations in just vacuum, or in ordinary matter and neutrino by interacting with them. Physicsists has some good theory about how neutrino oscillates in vacuum and matter, but how neutrino(s) would interact with itself(themselves) is still very active subfield by 2010s.
