Mu-neutrino & tau-neutrino mixing/scattering

  • Thread starter kokolovehuh
  • Start date
In summary, mu-neutrino and tau-neutrino mixing/scattering is the process of muon neutrinos and tau neutrinos interacting and potentially changing into each other due to their small mass. This occurs through a phenomenon called neutrino oscillation, which provides evidence for neutrino mass and is studied through experiments using large detectors. The significance of this mixing/scattering lies in its implications for our understanding of the Universe and its particles, as well as practical applications in astrophysics and beyond the Standard Model.

Hi all,
I was wondering, is this scattering process even possible? Since we cannot mix the two neutrinos on one side due to lepton number conservation, we need to convert one of the neutrino to its anti-neutrino by crossing symmetry. To conserve tau&mu number we have:

tau-neutrino + anti tau -> anti mu-neutrino + mu

However, this does not conserve charges!

Am I getting something wrong here, or is this scattering not possible?
Thanks in advance :-)

Try to draw a Feynman diagram ;).
It is not possible.

tau-neutrino + anti tau -> W -> mu-neutrino + anti-mu is possible.
 

FAQ: Mu-neutrino & tau-neutrino mixing/scattering

1. What is mu-neutrino and tau-neutrino mixing/scattering?

Mu-neutrino and tau-neutrino mixing/scattering refers to the phenomenon of muon neutrinos and tau neutrinos interacting and potentially changing into each other. This is possible because neutrinos have a small mass and can change their flavor or type as they travel through space.

2. How does mu-neutrino and tau-neutrino mixing/scattering occur?

Mu-neutrino and tau-neutrino mixing/scattering occurs through a process known as neutrino oscillation. This is when a neutrino changes its flavor while traveling through space due to its mass and interactions with other particles.

3. What is the significance of mu-neutrino and tau-neutrino mixing/scattering?

Mu-neutrino and tau-neutrino mixing/scattering is significant because it provides evidence for the existence of neutrino mass and the phenomenon of neutrino oscillation. It also helps scientists better understand the properties and behavior of neutrinos, which are important particles in the Standard Model of particle physics.

4. How is mu-neutrino and tau-neutrino mixing/scattering studied?

Mu-neutrino and tau-neutrino mixing/scattering is studied through experiments that involve detecting and measuring the interactions of neutrinos. These experiments often use large detectors, such as the Super-Kamiokande detector in Japan, to observe the different types of neutrinos and their oscillations.

5. What are the implications of mu-neutrino and tau-neutrino mixing/scattering?

The implications of mu-neutrino and tau-neutrino mixing/scattering are significant for our understanding of the Universe and its fundamental particles. It can also have practical applications, such as in neutrino detectors used in astrophysics and in the search for new physics beyond the Standard Model.
