In summary, the article discusses the discovery that neutrinos and anti-neutrinos may oscillate differently, which has been a long-standing unresolved issue in physics. The LSND and MiniBoone experiments have provided evidence for this difference, but further research is needed to understand the implications on the Standard Model. The article also addresses the speculative explanations and misunderstandings surrounding this topic.

They don't. The article was just wrong, and the reporter didn't know what he was talking about.

Why do neutrinos and anti-neutrinos oscillate differently?
Whether they do or not, and if they do, why, is a long-standing unresolved issue. The LSND neutrino oscillation experiment back in the 1990's seemed to see an excess oscillation from anti-muon neutrino to anti-electron neutrino. More than was expected, and difficult to explain. The MiniBoone experiment which ran from 2002 to 2005 looked at muon neutrino to electron neutrino, and to everyone's relief did not see an excess. But then they switched to using antineutrinos, and got a result confirming the one from LSND! This seemed to imply that neutrinos and antineutrinos behave differently.

See here and here for a summary.
 

FAQ: Why Do Neutrinos and Anti-Neutrinos Oscillate Differently?

1. Why do neutrinos and anti-neutrinos oscillate differently?

Neutrinos and anti-neutrinos are subatomic particles that have a property called "flavors" which can change as they travel through space. This phenomenon is known as neutrino oscillation. Neutrinos and anti-neutrinos oscillate differently because they have opposite charges and spin, which affects how they interact with other particles and their environment.

2. What causes neutrino oscillation?

Neutrino oscillation is caused by a mismatch between the mass and flavor states of neutrinos and anti-neutrinos. As these particles travel through space, they interact with other particles which can change their flavor state, leading to oscillation between different flavors (electron, muon, and tau).

3. How do we know that neutrinos and anti-neutrinos oscillate differently?

Scientists have conducted experiments using particle accelerators and detectors to study the behavior of neutrinos and anti-neutrinos. These experiments have shown that the oscillation patterns of neutrinos and anti-neutrinos are not symmetrical, indicating that they oscillate differently.

4. Can we control or manipulate neutrino oscillation?

At this point in time, we do not have the technology to control or manipulate neutrino oscillation. However, understanding this phenomenon is important in developing new technologies and applications that utilize neutrinos, such as in studying the properties of the universe or in medical imaging.

5. Are there any practical applications of studying neutrino oscillation?

Yes, there are many potential practical applications of studying neutrino oscillation. For example, neutrinos can be used to study the inner workings of the Sun, as they are produced in large quantities during nuclear reactions. Neutrino oscillation can also provide insights into the properties of matter and antimatter, which is crucial in understanding the origins of the universe.
