Neutrino-AntiNeutrino Collisions: EM Field?

In summary, photons are produced when a neutrino and an anti-neutrino collide due to the loop-induced vector boson and fermions. This can also occur in neutron-antineutron collisions, where a variety of hadron-antihadron particles can be produced. The production of photons in these collisions can be seen through a box diagram with a nu-nubar going in, a W on one side, and electrons on the other sides, resulting in two photons going out. However, this process is highly suppressed due to being one-loop. This discussion is not practical and is not a bigger problem than colliding beams of neutrinos and anti-neutrinos.

When a neutrino and an anti-neutrino collide they produce a photon , from what field does this photon come from. Photons are excitations of an EM field correct. or what about neutron anti-neutron collisions .

no they do not produce photons if they collide...neutron - antineutron will create lots of different things, there are a lot of hadron - antihadron particles which can be produced.

I think we had a related discussion here; the neutrino couples only to vector bosons, so a Z° pair can be created which will eventually decay in hadronic and leptonic final states.

You most certainly can produce photons in neutrino antineutrino collisions. You have a box diagram with a nu-nubar going in, a W on one side of the box, e's on the other 3 sides, and two photons going out.

thats what i thougt , so where is the EM field that produces these photons.

from the loop induced vector boson and the fermions

A box diagramm is one-loop and therefore highly suppressed.

yes, almost anything is allowed if one includes loops

And that's a bigger problem than colliding beams of neutrinos and anti-neutrinos??

Of course not, the whole discussion is not really practice-oriented :-)
 

1. What are neutrinos and antineutrinos?

Neutrinos and antineutrinos are subatomic particles that have no electric charge and very little mass. They are the smallest particles known to science and are considered to be fundamental building blocks of matter.

2. What happens when neutrinos and antineutrinos collide?

When neutrinos and antineutrinos collide, they can either scatter off of each other or annihilate each other, depending on their energy levels. In both cases, the collision produces an electromagnetic field.

3. How are neutrino-antineutrino collisions studied?

Neutrino-antineutrino collisions are studied using high-energy particle accelerators, such as the Large Hadron Collider (LHC) at CERN. These accelerators can produce beams of neutrinos and antineutrinos that are then collided with each other.

4. What is the significance of studying neutrino-antineutrino collisions?

Studying neutrino-antineutrino collisions can help scientists understand the fundamental properties of these particles, such as their mass and interactions with other particles. It can also provide insights into the early universe and the processes that govern it.

5. Are there any practical applications of neutrino-antineutrino collisions?

While there are no direct practical applications of neutrino-antineutrino collisions, the knowledge gained from studying these collisions can have implications in fields such as astrophysics and particle physics, and could potentially lead to new technologies in the future.
