Cladogenesis: Baryon-dark matter coincidence from branchings in moduli decay
We propose late-time moduli decay as the common origin of baryons and dark matter. The baryon asymmetry is produced from the decay of new TeV-scale particles, while dark matter is created from the (chain) decay of $R$-parity odd particles without undergoing any annihilation. The baryon and dark matter abundances are …
