Dark matter/antimatter

A friend asked me a question that I didn't know the answer to, so I thought I'd ask you all.

 

"What if dark matter is the product of matter-antimatter interaction in the early universe?"

 

Any information would be appreciated.

I think we would have noticed that, by adding up the momentum of the photons released when matter/antimatter collide. That's how we found the neutrino (for neutron decay).

I told her I didn't think she was correct, but I promised to ask. Thanks for the info :)
