Neutral particles with internal quantum numbers can mix with each other through virtual pair production.
The most important interaction mechanisms are the photoelectric effect, the Compton effect, and pair production.
It would have to be something propagating through tau space to affect pair production.
If a supernova destroys such a star, pair production will not be involved.
For example, neutrinos should exhibit Bremsstrahlung in the form of electron-positron pair production.
Adams believes the Earth is growing through a process called pair production.
But the main source of neutrinos at these high temperatures involves a process in quantum theory known as pair production.
Compton scattering and pair production are examples of two other competing mechanisms.
This radiation produced is itself extremely energetic, with many of the photons undergoing further pair production.
Another example is pair production in very strong electric fields, sometimes called vacuum decay.
