Possible Particle Pairs in Gravitational Pair Production: A Speculative Inquiry

[skippy1729]

Although there is no experimental evidence or QG theory, it is not unreasonable that very strong gravitational fields or very high energy gravitons would cause pair production of real particles. In view of the spin-2 nature of gravity, what might these pairs be? One electron, one positron and two neutrinos? Any educated speculation on this? Any research papers available?

Thanks, Skippy

PS is graviton --> 2 photons possible?

You can make electron-positron pairs, quark-antiquark pairs, pretty much anything you want.

In a sense Hawking radiation is just that

So its OK to have a spin-2 particle decay into two spin 1/2 particles?

Sure. Why not?

Sure. Why not?

I am confused. Isn't angular momentum (orbital and intrinsic) conserved in particle decay processes? Please note that I was asking about real not virtual pair production.
