Hello, This may sound silly, don't be afraid to let me know just how silly though! I've read that predictions are made using the standard model. I do not know the details of this process. I understand pair production occurs randomly in a vacuum, but I wondered if there was an underlying reason aside from a vacuum potential. Anyway, would there be a way to calculate characteristics/distribution of WIMPs (if they exist) assuming they decay in some way? I know WIMPs aren't supposed to interact electromagnetically, but could they still weakly?
